Technical Field

Embodiments of the present disclosure relate to an electrical system for a mobile power plant and a mobile power plant.

Background

With the development of the power industry, more and more equipment driven by electric power and power utilization scenes are adopted. Typically, power is provided by stationary power plants and grids; however, for a variety of reasons, stationary power plants and grids are unable to meet the power demands of consumers. For example, when the grid capacity is insufficient or the amount of power generated by a stationary power plant due to maintenance, malfunction, lack of fuel, etc., the power demand may exceed the grid capacity or the amount of power generated by the stationary power plant, thereby causing a power outage. For example, when a power grid or power equipment is damaged by a natural disaster such as a typhoon or an earthquake, power interruption or the like may occur. For another example, in some construction sites and well mine scenes without a power grid, the power demand cannot be met or the cost for laying the power grid is high.

On the other hand, a mobile power plant is a power plant that can be moved or transported. Therefore, the mobile power generation apparatus can be transported to various scenes where power is insufficient or no power, so that the power demand of the user can be satisfied.

The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

At present, mobile power generation devices can be transported to various scenes with insufficient or no power, so as to meet the power demand of users. However, the transportation means of the high-power mobile power generation apparatus is large in size, and under the restriction of natural conditions of roads or the requirement of road regulations, the transportation means with large size may not be able to smoothly and rapidly transport the mobile power generation apparatus to the area where the user is located. Thus, the size of the transportation means also becomes one of the main factors limiting the power generated by the mobile power generation apparatus. By making the layout of each component and system in the mobile power generation device more compact, the size of the transportation vehicle can be reduced, thereby satisfying the transportation requirements under various conditions while increasing the generated power.

The designer of the present application contemplates that, in addition to the layout of the prime mover, the generator, and the various auxiliary devices, the size and layout of the electrical system of the mobile power plant may be optimized to reduce the size of the vehicle of the mobile power plant. On the other hand, after the mobile power generation device is transported to a designated scene, the installation, maintenance and repair of the electrical system of the mobile power generation device are also complicated, and thus the use efficiency of the mobile power generation device is also reduced.

Based on this, the disclosed embodiments provide an electrical system for a mobile power plant and a mobile power plant. The mobile power generation device comprises a transport means and a generator; the electrical system includes: an electrical cabin arranged on the transport vehicle; and a generator switchgear, located within the electrical cabin, comprising generator switchgear configured to connect or disconnect a generator of the mobile power generation apparatus to an external load, the generator switchgear further comprising a first output configured to be electrically connected to the external load through a connection conductor, the first output comprising an electrical connection terminal or connector; the electric cabin comprises a first bottom plate, the generator switch cabinet is arranged on the first bottom plate, the first bottom plate comprises a first hollow-out part, and the orthographic projection of the generator switch cabinet on the first bottom plate is at least partially overlapped with the first hollow-out part. This electrical system is through setting up the first output of generator cubical switchboard in the bottom of the electric cabin body to the first fretwork portion on the accessible first bottom plate links to each other first output and external load electrical property, thereby usable and the transport means on the electric cabin body and the distance between the ground will first output be connected through connecting conductor and external load. In addition, the first output end of the generator switch cabinet is arranged at the bottom of the electric cabin, so that the space occupied by the first output end in the electric cabin can be reduced, and the space or the volume of the electric cabin can be further reduced. Therefore, the electrical system can reduce the size of the electrical system and reduce the difficulty of installation, overhaul and maintenance of the electrical system by optimizing the layout of the electrical system, so that the mobile power generation device adopting the electrical system can simultaneously meet various transportation requirements under the condition of higher power generation capacity, and the use efficiency of the mobile power generation device can also be improved.

Hereinafter, an electrical system for a mobile power generation apparatus and a mobile power generation apparatus provided in an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

An embodiment of the present disclosure provides an electrical system for a mobile power generation device. Fig. 1 is a schematic diagram of a mobile power generation device according to an embodiment of the present disclosure; fig. 2 is a schematic plan view of an electrical system for a mobile power plant according to an embodiment of the present disclosure; FIG. 3 is a side schematic view of an electrical system for a mobile power plant according to an embodiment of the present disclosure; fig. 4A and 4B are bottom schematic views of an electrical enclosure at a position of a dashed line frame AA in fig. 3 according to an embodiment of the disclosure.

As shown in fig. 1 and 2, the mobile power generation apparatus 200 includes a vehicle 210 and a generator 220; the generator 220 may be used to generate electricity, and the vehicle 210 may be used to carry and transport the generator 220 and the electrical system 100 for the mobile power plant 200. Electrical system 100 includes an electrical nacelle 110 and a generator switchgear cabinet 120; electrical nacelle 110 is disposed on transport vehicle 210, generator switchgear 120 is located within electrical nacelle 110 and includes generator switchgear 121; the generator switching device 121 serves to connect or disconnect the generator 220 of the mobile power generation apparatus 200 to or from an external load.

As shown in fig. 3, the generator switchgear 120 further includes a first output 122; the first output terminal 122 is configured to be electrically connected to an external load through the connection conductor 301. The first output 122 may be a terminal or a connector; the electric cabin 110 includes a first base plate 111, and the generator switchgear 120 is disposed on the first base plate 111. For example, the generator switch cabinet 120 may be fixed to the first base plate 111.

As shown in fig. 3 and 4A, the first bottom plate 111 includes a first hollow-out portion 1111, and an orthographic projection of the generator switchgear 120 on the first bottom plate 111 at least partially overlaps the first hollow-out portion 1111. That is to say, the power generator switch cabinet 120 is disposed at the position of the first hollow portion 1111, and the first output end 122 may be exposed from the first bottom plate 111 through the first hollow portion 1111 or may be disposed on the first hollow portion 1111, and the connection conductor passes through the first hollow portion 1111 and is connected to the first output end 122.

In the electrical system for a mobile power generation apparatus provided in the embodiment of the present disclosure, since the electrical cabin 110 is disposed on the transportation vehicle 210, and the carrying surface or the girder of the transportation vehicle 210 is located at a certain distance from the ground, the electrical system 100 is configured such that the first output end 122 of the generator switch cabinet 120 is disposed at the bottom of the electrical cabin 110, so that the first output end 122 can be connected to an external load through the connection conductor 301 by using the distance between the electrical cabin 110 on the transportation vehicle 210 and the ground.

On the one hand, when the first output terminal of the generator switch cabinet is disposed at the side of the electrical cabin, the first output terminal occupies a larger space in the electrical cabin in consideration of the bending radius, the safety distance, and the like of the connection conductor 301. However, the electrical system 100 provided by the embodiment of the disclosure may reduce the space occupied by the first output terminal 122 in the electrical cabin 110 by disposing the first output terminal 122 of the generator switch cabinet 120 at the bottom of the electrical cabin 110, and thus may reduce the space or volume of the electrical cabin 110.

On the other hand, when the first output end of the generator switch cabinet is arranged on the side surface of the electric cabin, because a certain distance (for example, about 1.5 meters) exists between the bearing surface of the transport tool or the bottom of the girder and the ground, and the sufficient safety distance needs to be ensured between the output end and the metal part of the transport tool 210, the position of the first output end may be high, and an installer needs to ascend a height tool to connect the connecting conductor with the first output end, so that the installation efficiency is low; and the climbing tools need to be transported together, which increases the volume and weight of the mobile power generation device. However, since the distance between the carrying surface of the transportation vehicle or the girder and the ground is just convenient for the installer to operate, the electrical system provided by the embodiment of the present disclosure uses the distance between the electrical cabin 110 on the transportation vehicle 210 and the ground to connect the first output terminal 122 with the external load through the connection conductor 301, thereby improving the installation efficiency. And when the maintenance and repair are needed, the maintenance efficiency and repair efficiency of the electrical system can be improved.

In summary, the electrical system can reduce the size of the electrical system and reduce the difficulty of installation, maintenance and repair of the electrical system by optimizing the layout of the electrical system, so that the mobile power generation device adopting the electrical system can meet various transportation requirements under the condition of higher generated power, and the service efficiency of the mobile power generation device can be improved.

In some examples, as shown in fig. 3, since the generator switchgear 120 is disposed on the first base plate 111, the first output terminal 122 is also located at the bottom of the generator switchgear 120.

In some examples, as shown in fig. 3, the first output 122 may include a connector so that it may be more conveniently connected to an external load. Of course, the first output terminal 122 may not include a connector, but may include a terminal.

In some examples, as shown in fig. 3, 4A and 4B, the electrical cabin 110 further includes a second bottom plate 112, the second bottom plate 112 is located on a side of the first bottom plate 111 away from the generator switch cabinet 120, the second bottom plate 112 includes a second hollow portion 1122, an orthographic projection of the first hollow portion 1111 on the second bottom plate 112 falls within the second hollow portion 1122, and the electrical cabin 110 further includes a first cover 1125 movably connected to the second bottom plate 112 and shielding the second hollow portion 1122. Thus, when the mobile power generator is transported, as shown in fig. 4B, the first cover 1125 may be closed to shield the second hollow 1122, so as to prevent impurities such as moisture and dust from entering the electric cabin 110 or between the first bottom plate 111 and the second bottom plate 112; when the mobile power generation apparatus is transported to a predetermined location, as shown in fig. 4A, an installer may open or move the first cover 1125 to connect the first output terminal 122 to the connection conductor through the second hollow 1122, thereby connecting to an external load.

In some examples, as shown in fig. 3, the second bottom plate 112 includes a central region 1120 and an edge portion 1121 positioned in the central region 1120, the central region 1120 of the second bottom plate 112 is spaced apart from the first bottom plate 111, and the edge portion 1121 of the second bottom plate 112 is fixedly connected to the edge of the first bottom plate 111.

In some examples, as shown in fig. 3 and 4A, the first output end 122 includes at least one electrical terminal 1220, and the first base plate 111 includes at least one first hollow 1111 disposed corresponding to the at least one electrical terminal 1220; the second bottom plate 112 includes a second hollow-out portion 1122, and the orthographic projection of the first hollow-out portion 1111 on the second bottom plate 112 falls within the second hollow-out portion 1122. That is, the second hollow portion 1122 has a large size, so that it is convenient for an installer to install.

For example, as shown in fig. 4A, each of the power connection terminals 1220 may have a circular or rectangular planar shape, the first hollow portion 1111 may have a circular or rectangular planar shape, and the second hollow portion 1122 may have a rectangular planar shape. Of course, the embodiments of the present disclosure include, but are not limited to, the planar shapes of the first hollow portion and the second hollow portion may be set according to actual needs.

In some examples, as shown in fig. 4B, a first edge 1125A of the first cover 1125 is hinged to a second edge 1122A of the second hollow 1122, and the first cover 1125 is configured to flip over along the first edge 1125A to facilitate handling by an installer.

For example, the above-mentioned hinge may be implemented by a pivot shaft, a hinge chain, or the like, and the disclosed embodiments are not particularly limited herein. For example, the first cover may be connected to the second hollow through-out portion in other ways, and the first cover may be moved or folded relative to the second edge, so as to achieve the effect of opening the first cover.

In some examples, as shown in fig. 1 and 2, the mobile power plant 200 further includes a generator nacelle 230, the electrical nacelle 110 being disposed adjacent to the generator nacelle 230 and sharing the first side plate 114; that is, the electrical nacelle 110 is connected to the generator nacelle 230, and only one first side plate 114 is disposed between the electrical nacelle 110 and the generator nacelle 230 for separation.

Fig. 5 is an enlarged schematic view of the electrical system shown in fig. 2 at the location of the dashed box BB. As shown in fig. 2 and 5, the generator switchgear 120 includes a first service opening 123; the first side plate 114 includes a first opening 1141, the first opening 1141 is disposed corresponding to the first access opening 123, and an orthographic projection of the first access opening 123 on the first side plate 114 at least partially overlaps the first opening 1141, and is configured to enable a person to access the generator switchgear 121 in the generator switchgear 120 through the first opening 1141 and the first access opening 123. Thus, the first opening 1141 and the first service opening 123 have a certain area, and the overlapping area between the first opening 1141 and the first service opening 123 is also large (the overlapping area is more than 80% of the first service opening 123) or even completely overlapped, so that a person can enter. The electrical system 100 further includes a first service partition 131 removably mounted to the first side plate 114 and covering the first opening 1141.

Generally, because the equipment in the generator switch cabinet needs to be overhauled, the generator switch cabinet needs to be provided with an overhaul inlet (similar in function to the first overhaul opening) and an overhaul door located on the overhaul inlet, and an overhaul channel for personnel to enter and exit needs to be reserved outside the generator switch cabinet, so that a large space in an electric cabin can be occupied.

In the electrical system 100 provided in this example, an orthographic projection of the first service opening 123 on the first side plate 114 at least partially overlaps the first opening 1141, and the first service partition 131 is detachably mounted on the first side plate 114 and blocks the first opening 1141. Therefore, when the mobile power generation device normally works, the first access partition board 131 can shield the first opening 1141, so as to separate the electric cabin 110 from the generator cabin 230, and simultaneously separate and seal the electric cabin 110 from the generator cabin 230; for example, an air conditioner may be disposed within the electrical enclosure 110 to control the temperature of the electrical enclosure 110 to between 25 degrees celsius and 35 degrees celsius to provide advantages for heat dissipation and safe operation of the electrical equipment within the electrical enclosure 110. When the mobile power generation device is overhauled or installed, personnel can use the overhaul space of the generator cabin 230 to enter the generator switch cabinet 120 from the generator cabin 230 and overhaul the generator switch equipment 121 in the generator switch cabinet 120. Accordingly, the electrical system 100 provided in this example can further reduce the volume or size of the electrical cabin 110, making the layout more compact, so that the mobile power generation apparatus using the electrical system can satisfy various transportation requirements while having a higher generated power, and can also improve the use efficiency of the mobile power generation apparatus.

It should be noted that, because the shape of the generator 220 is generally irregular, and considering the requirements of safety, maintenance, wiring, air intake, ventilation, etc., the volume of the generator cabin 230 itself is much larger than that of the generator 220, so that there is a large maintenance space.

For example, as shown in fig. 5, the first service partition 131 may be detachably mounted on the first side plate 114 by screws 1315 and block the first opening 1141. Of course, the disclosed embodiments include, but are not limited to, the first service partition may also be detachably mounted on the first side plate by other means.

In some examples, as shown in fig. 2, the electrical system 100 may further include: and a neutral point equipment cabinet 140 located inside the electric cabin 110 and including a neutral point equipment 141, wherein the neutral point equipment 141 is configured to be connected to a neutral point of the generator 220, the neutral point equipment cabinet 140 includes a second service opening 143, the first side plate 114 includes a second opening 1142 disposed corresponding to the second service opening 143, and an orthographic projection of the second service opening 143 on the first side plate 114 at least partially overlaps the second opening 1142. Similarly, the second opening 1142 and the second service opening 143 are also configured to allow personnel to service the neutral point apparatus 141 in the neutral point apparatus cabinet 140 through the second opening 1142 and the second service opening 143. Thus, the second opening 1142 and the second service opening 143 have a certain area, and the overlapping area between the second opening 1142 and the second service opening 143 is also large (the overlapping area is more than 80% of the second service opening 143), even completely overlapping, so that personnel can enter. The electrical system 100 also includes a second service partition 132 removably mounted to the first side plate 114 and covering the second opening 1142.

In the electrical system 100 provided in this example, the orthographic projection of the second service opening 143 on the first side plate 114 at least partially overlaps the second opening 1142, and the second service partition 132 is detachably mounted on the first side plate 114 and blocks the second opening 1142. Thus, when the mobile power generation apparatus is operating normally, the second access partition 132 can block the second opening 1142, so as to separate the electrical cabin 110 from the generator cabin 230, and simultaneously separate and seal the electrical cabin 110 from the generator cabin 230. When the mobile power generation device is overhauled or installed, personnel can use the overhaul space of the generator cabin 230 to enter the neutral point equipment cabinet 140 from the generator cabin 230 and overhaul the neutral point equipment 141 in the neutral point equipment cabinet 140. Accordingly, the electrical system 100 provided in this example can further reduce the volume or size of the electrical cabin 110, making the layout more compact, so that the mobile power generation apparatus using the electrical system can satisfy various transportation requirements while having a higher generated power, and can also improve the use efficiency of the mobile power generation apparatus.

In some examples, as shown in fig. 2, the electrical system 100 further includes a start-up equipment cabinet 150, the start-up equipment cabinet 150 being located within the electrical cabin 110 and including a start-up equipment 151, the start-up equipment 151 being configured to start the prime mover 240. The first side plate 114 further includes a main body portion 1143 located between the first opening 1141 and the second opening 1142, and the starting equipment cabinet 150 is disposed between the generator switch cabinet 120 and the neutral point equipment cabinet 140 and adjacent to the main body portion 1143 of the first side plate 114.

Fig. 6A and 6B are enlarged schematic views of an electrical enclosure provided in an embodiment of the disclosure at a dashed box CC in fig. 3.

In some examples, as shown in fig. 3, 6A, and 6B, the electrical system 100 further includes an auxiliary power distribution cabinet 165 located within the electrical enclosure 110 and including auxiliary power distribution equipment 166, the auxiliary power distribution equipment 166 configured to provide power to the auxiliary equipment; the auxiliary switch cabinet 165 further includes a second output 1652 configured to connect to auxiliary equipment, the second output 1652 may include a terminal or connector; the first bottom plate 111 comprises a third hollow-out part 1113, and the orthographic projection of the auxiliary power distribution cabinet 165 on the first bottom plate 111 at least partially overlaps with the third hollow-out part 1113. That is, like the first output terminal 122, the second output terminal 1652 is also located at the bottom of the auxiliary distribution cabinet 165, and can be connected to the auxiliary equipment through the connection conductor 302.

In the electrical system for a mobile power generation apparatus provided in the embodiment of the present disclosure, since the electrical cabin 110 is disposed on the transportation vehicle 210, and the carrying surface or the girder of the transportation vehicle 210 is located at a certain distance from the ground, the electrical system 100 can utilize the distance between the electrical cabin 110 on the transportation vehicle 210 and the ground by disposing the second output end 1652 of the auxiliary power distribution cabinet 165 at the bottom of the electrical cabin 110, so that the second output end 1652 can be connected to the auxiliary equipment through the connection conductor 302.

On the one hand, when the second output terminal of the auxiliary power distribution cabinet is arranged on the side face of the electric cabin, the second output terminal can occupy a larger space in the electric cabin in consideration of the bending radius, the safety distance and other factors of the connecting conductor. However, the electrical system 100 provided by the embodiment of the disclosure may reduce the space occupied by the first output terminal 1652 in the electrical cabin 110 by disposing the second output terminal 1652 of the auxiliary power distribution cabinet 165 at the bottom of the electrical cabin 110, and further may reduce the space or volume of the electrical cabin 110.

On the other hand, when the second output end of the auxiliary power distribution cabinet is arranged on the side surface of the electric cabin, the position of the second output end may be high because the bearing surface of the transport tool or the girder has a certain distance (for example, about 1.5 meters) from the ground, and an installer needs to ascend a height tool to connect the connecting conductor with the second output end, so that the installation efficiency is low; and the climbing tools need to be transported together, which increases the volume and weight of the mobile power generation device. However, since the distance between the carrying surface of the vehicle or the girder and the ground is just convenient for the installer, the electrical system provided by the embodiment of the present disclosure uses the distance between the electrical cabin 110 on the vehicle 210 and the ground to connect the second output end 1652 to the auxiliary equipment through the connection conductor 302, thereby improving the installation efficiency. And when the maintenance and repair are needed, the maintenance efficiency and repair efficiency of the electrical system can be improved.

In some examples, as shown in fig. 3, 6A and 6B, the electrical cabin 110 further includes a second bottom plate 112, the second bottom plate 112 is located on a side of the first bottom plate 111 away from the auxiliary power distribution cabinet 165, the second bottom plate 112 includes a fourth hollow portion 1124, and an orthographic projection of the third hollow portion 1113 on the second bottom plate 112 falls within the fourth hollow portion 1124; the electrical enclosure 110 may further include a second cover 1126 detachably connected to the second base 112 and covering the fourth hollow 1124. Thus, when the mobile power generation apparatus is transported, as shown in fig. 6B, the second cover 1126 may be in a closed state to shield the fourth hollow 1124, so as to prevent impurities such as moisture, dust, etc. from entering the electric cabin 110 or between the first bottom plate 111 and the second bottom plate 112; when the mobile power plant is transported to a desired location, as shown in fig. 6A, the installer may open the second cover 1126, connect the second output 1652 to the connection conductor via the fourth cutout 1124, and thus to the auxiliary equipment.

In some examples, as shown in fig. 6A, similarly, the second output end 1652 includes at least one electrical terminal 16520, and the first base plate 111 includes a plurality of third hollow portions 1113 arranged in a one-to-one correspondence with the at least one electrical terminal 16520; the second bottom plate 112 includes a fourth hollow portion 1124, and the orthographic projections of the third hollow portions 1113 on the second bottom plate 112 all fall within the fourth hollow portion 1124. That is, the size of the fourth hollow 1124 is large, so that it is convenient for an installer to install.

For example, as shown in fig. 6A, each electrical terminal 16520 may have a circular planar shape, the third hollow 1113 may have a circular or rectangular planar shape, and the fourth hollow 1124 may have a rectangular planar shape. Of course, the embodiments of the present disclosure include, but are not limited to, the planar shapes of the third hollow portion and the fourth hollow portion may be set according to actual needs.

In some examples, as shown in fig. 6B, a third edge 1126A of the second cover panel 1126 is hingedly connected to a fourth edge 1124A of the fourth hollowed portion 1124, the second cover panel 1126 being configured to be flipped over along the third edge 1126A to facilitate handling by an installer.

For example, the above-mentioned hinge may be implemented by a pivot shaft, a hinge chain, or the like, and the disclosed embodiments are not particularly limited herein.

For example, the second cover plate may be connected to the fourth hollow portion in other ways, and the second cover plate may move or fold relative to the fourth edge, so as to achieve the effect of opening the second cover plate.

In some examples, as shown in fig. 2, electrical system 100 further includes an auxiliary power transformation cabinet 160, auxiliary power transformation cabinet 160 being located within electrical nacelle 110 and including an auxiliary power transformation device 161, auxiliary power transformation device 161 being configured to convert the first voltage output by generator 220 to a second voltage. The electrical system 100 also includes an auxiliary power transformation switchgear 162 located within the auxiliary power transformation equipment cabinet 160 and configured to turn on or off the auxiliary power transformation equipment 161. Thus, the auxiliary power transformation device 161 is configured to convert the first voltage output by the generator 220 into the second voltage, and then supply power to other auxiliary devices; and the auxiliary power transformation switchgear 162 may turn the auxiliary power transformation equipment 161 on or off. In addition, since the auxiliary power transformation equipment 161 and the auxiliary power transformation switchgear 162 are both disposed in the auxiliary power transformation cabinet 160, it is not necessary to separately dispose an electric cabinet in which the auxiliary power transformation switch is disposed, so that the integration level of the electric cabin can be improved, and the volume of the electric cabin can be reduced.

In some examples, the auxiliary power transformation equipment 161 and the auxiliary power transformation switchgear 162 are sequentially disposed in the auxiliary power transformation cabinet 160 in a direction perpendicular to the first base plate 111; the auxiliary power transformation equipment 161 is disposed below the auxiliary power transformation switchgear 162, that is, the auxiliary power transformation equipment 161 is located on the side of the auxiliary power transformation switchgear 162 close to the first base plate 111. Therefore, although the height of the auxiliary power transformation cabinet 160 may be increased, the area occupied by the auxiliary power transformation cabinet 160 is not changed, so that the integration level of the electric enclosure can be improved, and the volume of the electric enclosure can be reduced.

For example, the output of the auxiliary power transformation device 161 can be wired to the auxiliary power distribution device 166 to provide power at the second voltage to the auxiliary device via the auxiliary power distribution device 166.

In some examples, the auxiliary power transformation device 161 may include a transformer, the first voltage being greater than the second voltage. For example, the first voltage may be 10KV-20KV, and the second voltage may be 200V-500V.

In some examples, as shown in fig. 2, the electrical system 100 further includes: an uninterruptible power supply cabinet 170, the uninterruptible power supply cabinet 170 being located within the electrical cabin 110 and including uninterruptible power supply equipment 171. The electrical system 100 also includes a battery 172 located within the ups cabinet 170. Therefore, in the electrical system 100, the uninterruptible power supply equipment 171 and the storage battery 172 are integrated in the same uninterruptible power supply cabinet 170, so that a tray cabinet for placing the storage battery is not required to be separately arranged, the integration level of the electrical cabin can be improved, and the volume of the electrical cabin can be reduced.

For example, the uninterruptible power supply 171 may be an ac or dc uninterruptible power supply. The ups device 171 may provide power to control devices, protection devices, etc. of the generator and prime mover (e.g., turbine engine) through the power distribution device 178 to control and protect the generator and prime mover when the start-up power and the second voltage power are removed.

In some examples, as shown in fig. 1 and 2, the mobile power plant 200 includes a prime mover 240; the electrical system 100 further comprises: a generator control protection cabinet 180 and a prime mover control protection cabinet 190; generator control protection cabinet 180 is located within electrical nacelle 110 and includes generator control protection equipment 181, generator control protection equipment 181 configured to control and protect generator 220; the prime mover control protection cabinet 190 is located within the electrical nacelle 110 and includes prime mover control protection equipment 191, the prime mover control protection equipment 191 configured to control and protect the prime mover 240.

In some examples, as shown in fig. 1 and 2, the electrical system 100 may further include: satellite time setting equipment 182, generator grid-connected control equipment 183 and closed circuit television equipment 184. On one hand, the satellite time synchronization equipment 182 can be used for time synchronization of the generator control protection equipment 181 and the prime mover control protection cabinet 190, so that operating personnel can conveniently perform data analysis on the operation condition and the fault of the generator 200; the generator grid tie control device 183 may be used to run the generator 220 in parallel with other generators or in parallel with the grid; the closed circuit television equipment 184 can be used for remote monitoring of the operating conditions and environmental conditions of the mobile power plant or of equipment outside the mobile power plant.

For example, the satellite time synchronization device 182 may be a GPS time synchronization device, and may also be a beidou time synchronization device; in addition, the satellite time-setting device 182 can adopt a hard-wired time-setting or a network time-setting.

In some examples, as shown in fig. 1 and 2, the mobile power generation apparatus 200 includes a prime mover compartment 250, the prime mover 240 being located within the prime mover compartment 250; the electrical system 100 further comprises: a prime mover data collection box 195 configured to detect and display operating parameters of the prime mover 240, the prime mover data collection box 195 being disposed adjacent the prime mover 240, e.g., within the prime mover compartment 240. Therefore, the prime mover data acquisition module originally disposed inside the electric nacelle 110 can be moved to the prime mover nacelle 240, thereby reducing the volume of the electric nacelle 110.
