Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The technical background of the embodiments of the present invention is described below.
Referring to fig. 1, a power supply schematic diagram of UPS equipment and air conditioning equipment of an integrated data center in the prior art is shown. The UPS equipment comprises an electromagnetic interference (Electro Magnetic Interference, EMI) circuit 1, a rectifying circuit 1 and an inverter circuit 1, wherein alternating current of a mains supply grid is output to core equipment after being processed by each circuit of the UPS so as to supply power for the core equipment, namely, the core equipment 1 to the core equipment N; the air conditioner includes an EMI circuit 2, a rectifying circuit 2, an inverter circuit 2, a compressor, etc., and of course, the air conditioner also includes a blower, a heater, etc., but not shown in fig. 1, and ac power of a utility grid is output to the compressor, etc. after being processed by the EMI circuit 2, the rectifying circuit 2, and the inverter circuit 2 of the air conditioner, to supply power to the compressor, etc. It can be seen that the UPS and air conditioning units are completely independent units in the integrated data center, thus each occupying a large portion of the space of the integrated data center, making the available space for the core units smaller, the performance of the integrated data center lower, or the total volume of the current integrated data center increasing, thereby requiring a larger space for placement.
In view of this, the embodiment of the present invention provides a controller integrated system, in which the first inverter circuit and the second inverter circuit can both be connected to a load, then one of the inverter circuits can be used as UPS equipment to supply power to the core equipment, and the other inverter circuit can be used to supply power to the air conditioning equipment, so as to ensure that the integrated data center can normally operate.
The following describes the technical scheme provided by the embodiment of the invention with reference to the accompanying drawings.
Referring to fig. 2, an embodiment of the present invention provides a controller integrated system. The system may include an EMI circuit, a rectifying circuit, a first inverter circuit, and a second inverter circuit. The input end of the EMI circuit is connected to the ac power supply, the output end of the EMI circuit is connected to the input end of the rectifying circuit, the output end of the rectifying circuit is connected to the first inverter circuit and the second inverter circuit, the output end of the first inverter circuit and the output end of the second inverter circuit are respectively connected to different loads, that is, the first inverter circuit in fig. 2 is connected to the load 1, and the second inverter circuit is connected to the load 2. The ac power source may be a utility power grid, or any other power source capable of providing ac power, which is not limited in this embodiment of the present invention.
In the embodiment of the invention, the EMI circuit can carry out filtering treatment on the mains supply input by the alternating current power supply and output the treated mains supply to the rectifying circuit. The EMI circuit carries out filtering treatment on the commercial power and can filter harmonic interference of the alternating current power supply; in addition, the EMI circuit can also prevent electromagnetic harmonic waves generated by the later-stage circuit from affecting the controller integrated system so as to meet the use requirements of electromagnetic compatibility (Electro Magnetic Compatibility, EMC) and the like. The mains voltage may be a single-phase or three-phase ac voltage, and the voltage of the EMI output may be a single-phase or three-phase ac voltage, respectively.
In the embodiment of the invention, the rectifying circuit can carry out power factor adjustment on the commercial power after the processing output by the EMI circuit and carry out rectifying processing on the commercial power. The rectifier circuit may be, for example, a power factor correction (Power Factor Correction, FPC) rectifier circuit. The rectification circuit can also comprise a high-frequency conversion sub-circuit, and the power factor of the commercial power is regulated by the high-frequency conversion sub-circuit so as to increase the power factor and improve the efficiency of the commercial power. The rectifying circuit rectifies the commercial power to output a stable direct current voltage to the first inverter circuit and the second inverter circuit. The rectifying circuit and the first inverter circuit and the second inverter circuit can be connected through a direct current bus, and the direct current bus has an energy buffering function, namely, when the energy output by the rectifying circuit cannot be received by the first inverter circuit or the second inverter circuit, the direct current bus can buffer the energy. The dc bus may be realized by, for example, a component capable of absorbing energy, such as a capacitor or an inductor.
In the embodiment of the invention, the first inverter circuit and the second inverter circuit can both convert the direct-current voltage output by the rectifying circuit into alternating current which can be used by the load and output the alternating current to the load connected with the first inverter circuit and the second inverter circuit, so that the load is supplied with power. The first inverter circuit and the second inverter circuit may each be a single-phase inverter circuit or a three-phase inverter circuit, and in particular, the single-phase inverter circuit or the three-phase inverter circuit may be configured according to a specific load.
Specifically, when the first inverter circuit is used as a UPS device to supply power to a core device in the integrated data center, the first inverter circuit may be a voltage-type inverter circuit, and the output voltage is an ac voltage with constant voltage and constant frequency, because of the special requirement of the core device, that is, the core device can only be supplied with power by the output voltage.
Specifically, when the second inverter circuit supplies power to the air conditioning equipment in the integrated data center, the air conditioning equipment is not required to supply power by the output voltage or the output current, and thus the second inverter circuit may be a voltage type inverter circuit or a current line type inverter circuit. However, when the second inverter circuit supplies power to the air conditioning apparatus, that is, the first inverter circuit acts as a frequency converter of the air conditioning apparatus, the electric power output by the second inverter circuit must include both an alternating current with constant voltage and constant frequency and an alternating current with variable frequency and variable voltage, for example, when the compressor in the air conditioning apparatus is started or the frequency is changed for speed regulation, the second inverter circuit needs to output the alternating current with variable frequency and variable voltage; in the air conditioner, when the compressor and other devices are stably operated, the second inverter circuit needs to output an alternating current with constant voltage and constant frequency. When the second inverter circuit is a current type inverter circuit, the second inverter circuit is used for outputting alternating current with constant voltage and constant frequency or outputting alternating current with variable frequency and variable voltage; alternatively, when the second inverter circuit is a voltage-type inverter circuit, the second inverter circuit is configured to output an alternating-current voltage having a constant voltage and a constant frequency, or configured to output an alternating-current voltage having a variable frequency and a variable voltage.
Referring to fig. 3, a schematic connection diagram of the controller integrated system with the bypass circuit added to fig. 2 is shown. In which one end of the bypass circuit is connected to an ac power supply and the other end is connected to a load to which the first inverter circuit is connected or a load to which the second inverter circuit is connected, only the case where the other end of the bypass circuit is connected to the load to which the first inverter circuit is connected is shown in fig. 3, but it is to be understood that the bypass circuit may be connected to the load to which the second inverter circuit is connected.
Specifically, when the value of the voltage output by the bypass circuit and the frequency of the voltage are within the preset range, the load 1 connected with the first inverter circuit can be powered by the bypass circuit, that is, the first inverter circuit does not supply power to the load connected with the first inverter circuit, and the load 1 is powered by the bypass circuit instead of the first inverter circuit, so that the value of the voltage and the frequency of the voltage output by the bypass circuit to the load 1 can be almost consistent with the value of the voltage and the frequency of the voltage input by the mains supply, and the loss of electric energy can be reduced by directly outputting through the bypass circuit, that is, the efficiency of the electric energy is improved. In addition, when the value of the voltage output by the bypass circuit and the frequency of the voltage are not within the preset range, the voltage cannot be directly output through the bypass circuit in order to ensure the safety of the load. The preset range can be a range capable of ensuring that the commercial power directly supplies power to the load safely, and the range can be set according to the result of experimental test or according to experience. Of course, the load 2 connected to the second inverter is supplied with power by the bypass circuit, similarly to the case of supplying the load 1 connected to the first inverter by the bypass circuit, and thus, for this purpose, reference is made to the description of supplying the load 1 by the bypass circuit, which is not repeated here. When the bypass circuit supplies power to the load, the bypass circuit may supply power to the load, and the bypass circuit may supply power to the load.
In the embodiment of the invention, the bypass circuit can also supply power to the load 1 or the load 2 when the first inverter circuit or the second inverter circuit fails, so as to ensure that the load can continuously run.
Referring to fig. 4, on the basis of the embodiment corresponding to fig. 3, the bypass circuit may further include a first bypass circuit and a second bypass circuit, where one end of the first bypass circuit is connected to the ac power supply, and the other end of the first bypass circuit is connected to the load connected to the first inverter circuit; one end of the second bypass circuit is connected with an alternating current power supply, and the other end of the second bypass circuit is connected with a load connected with the second inverter circuit.
Specifically, when the voltage value and the frequency of the voltage output by the first bypass circuit are within the preset range, the load 1 connected to the first inverter circuit can be directly powered through the first bypass circuit, when the voltage value and the frequency of the voltage output by the second bypass circuit are within the preset range, the load 2 connected to the first inverter circuit can also be directly powered through the second bypass circuit, that is, the first bypass circuit and the second bypass circuit respectively power the load 1 and the load 2 and are independent of each other, so that no matter what working state the load 1 and the load 2 are, for example, the load 1 is core equipment, the load 2 is air conditioning equipment, and when the air conditioning equipment is frequently started or regulated in a variable frequency mode, the air conditioning equipment cannot be directly powered through the second bypass circuit, but the core equipment is not influenced, that is, the core equipment can still supply power through the first bypass circuit.
Referring to fig. 5, a schematic diagram of the connection of the controller integrated system with the charge/discharge circuit and the battery added to the system of fig. 3 is shown. One end of the charging and discharging circuit is connected with the battery, and the other end of the charging and discharging circuit is connected with the output end of the rectifying circuit.
Specifically, when the ac power source supplies power normally, the charge-discharge circuit may charge the battery by the electric energy output from the output terminal of the rectifying circuit. Specifically, when the ac power supply fails, that is, the load cannot obtain electric energy from the ac power supply at this time, the charge-discharge circuit may obtain energy from the battery and output the energy to the dc bus, so that the first inverter circuit and/or the second inverter circuit may obtain electric energy from the dc bus to supply power to the corresponding load. Of course, because the battery can store limited electric energy, the battery can not supply power to a plurality of loads for a long time, and therefore, when the battery is used for supplying power, the load needing to be supplied with power can be selectively selected. For example, when the load 1 is a core device and the load 2 is an air conditioner, the power can be continuously supplied to the core load for a long time through the battery, the air conditioner can be intermittently supplied, and the specific time of supplying the power to the air conditioner can be determined according to the current temperature of the integrated data center and the electric quantity of the battery. For example, when the current temperature of the integrated data center is greater than a certain threshold, in order to ensure the operation safety of each device in the integrated data center, power can be supplied to the air conditioning device at the moment so as to reduce the temperature, and when the temperature is reduced to a safer temperature, the power supply to the air conditioning device can be stopped. Therefore, the normal operation of the core equipment at the position for a longer time can be ensured, and the operation safety of the integrated data center can be ensured.
In the embodiment of the invention, when the first inverter circuit and/or the second inverter circuit supply power to the load, an energy feedback phenomenon may also occur, for example, the air conditioner compressor feeds back energy to the direct current bus during braking, and then the charging and discharging circuit can charge the battery through the energy fed back by the part, so that the energy can be more fully utilized.
Referring to fig. 6, a schematic diagram of the connection of the controller integrated system for controlling the monitor circuit and the auxiliary power circuit is added on the basis of fig. 5. One end of the auxiliary power circuit is connected to the ac power supply, and the other end of the auxiliary power circuit is connected to the rectifying circuit, the first inverter circuit, the second inverter circuit, and the control and monitoring circuit, however, the auxiliary power circuit may be connected to circuits other than the above circuits in the controller integrated system, that is, circuits requiring power supply may be connected to the auxiliary power circuit, such as a bypass circuit, a charge/discharge circuit, or a battery, in addition to the circuits connected to the auxiliary power circuit shown in fig. 6, which is not limited in this embodiment of the present invention.
In particular, the auxiliary power supply circuit may be used to power the circuitry to which it is connected. For example, the auxiliary power circuit may power the rectifier circuit, the first inverter circuit, the second inverter circuit, and the control and monitor circuit. The auxiliary power circuit can obtain electric energy from the alternating current power supply, the bypass circuit, the battery and/or the direct current voltage output by the rectifying circuit, namely, the electric energy obtained through the modes is used for supplying power to the circuit connected with the auxiliary power circuit.
The control and monitoring circuit is used for collecting the operation parameters of the system and the operation parameters of the load. In particular, the operating parameters may include voltage, current, charge of the battery, charge-discharge status, power mode, and/or operating parameters of the load. The voltage may be, for example, an input voltage or an output voltage of each circuit, such as an input voltage or an output voltage of an EMI circuit; the power supply mode comprises a mains supply mode, a bypass mode and a battery mode, wherein the mains supply mode is a mode of supplying power to a load through electric energy output by the first inverter circuit or the second inverter circuit, the bypass mode is a mode of supplying power to the load through the bypass circuit, and the battery mode is a mode of supplying power to the load through a battery; the operation parameters of the load may include a relevant state or parameter of the load when the load is operated, for example, when the load is an air conditioning device, the operation parameters may include a compressor operation state, a fan state, a heater state, a humidifier state, a wind speed set by the air conditioning device, a temperature and/or a humidity, etc. in the air conditioning device, and when the load is a core device, the operation parameters may include a start-up or a shut-down of the core device, etc. of course, other possible parameters may also be included, which is not limited by the embodiment of the present invention.
The control monitoring circuit can also collect operation parameters to control the system, namely, control commands are issued to the circuits of all parts in the system, so that the circuits of all parts in the system operate according to the corresponding control commands. Specifically, the control and monitoring circuit may set the power supply mode of the load and/or the operation parameters of the load according to the operation parameters. Of course, the control and monitoring circuit can also control other circuits in the controller integrated system, such as switching of bypass circuits, etc. The control monitoring circuit can also output the operation parameters to the display unit, so that the display unit displays the operation parameters, and an operator can visually check the operation state of the controller integrated system or the integrated data center.
Specifically, when the output voltage and frequency of the first inverter circuit or the second inverter circuit are stable, that is, the voltage is constant and the frequency is constant, and the voltage and frequency of the bypass circuit output are also stable within the safe power supply range, the control monitoring circuit can control the first inverter circuit or the second inverter circuit to switch to the bypass circuit output, that is, the load equivalent to the load of the first inverter circuit or the load of the second inverter circuit directly supplied with the commercial power. When the operation parameters indicate that the voltage and the frequency output by the bypass circuit exceed the safe power supply range, the control monitoring circuit can control the first inverter circuit or the second inverter circuit to be immediately switched to output and supply power. Therefore, the loss of the controller integrated system can be reduced in the bypass mode, the overall efficiency is improved, and the operation safety of the controller integrated system and the load can be ensured.
Specifically, when the ac power supply is powered down, the control and monitoring circuit can control switching to supply power to the load through the battery. The battery discharges electric energy to the direct current bus through the battery charging and discharging circuit, the first inverter circuit and the second inverter circuit can simultaneously acquire energy from the direct current bus, direct current voltage is converted into alternating current and is output respectively, and when the load 1 is core equipment, the first inverter circuit outputs alternating current voltage with constant voltage and constant frequency to supply power for the core equipment; when the load 2 is an air conditioner, the second inverter circuit may output an alternating current with a variable voltage and a variable frequency when the compressor in the air conditioner is started, and output an alternating current with a constant voltage and a constant frequency after the compressor is stable in operation. In the battery mode, the control and monitoring circuit can also determine whether the second inverter circuit outputs according to the current temperature, humidity, battery capacity and other information of the system, and the control and monitoring circuit can also set the temperature, wind speed, humidity and other parameters of the air conditioning equipment according to the current temperature, humidity and other information of the system.
In summary, in the embodiment of the present invention, the first inverter circuit and the second inverter circuit can both be connected to a load, so that one inverter circuit can be used as UPS equipment to supply power to the core equipment, and the other inverter circuit can be used to supply power to the air conditioning equipment, so as to ensure that the integrated data center can normally operate. Meanwhile, whether the air conditioning equipment is powered or not can be determined comprehensively according to the current temperature and the battery power of the integrated data center, so that the normal operation of the core equipment at the position for a longer time can be ensured, and the operation safety of the integrated data center can be ensured.
