Description

Distribution system for distribnting electricity The invention relates to a distribution system comprising a sector arranged to distribute electricity to a plurality of loads over at least one sector power line, at least one measurement means to measure characteristics of the electricity in the sector and a first communication 1 0 device arranged to send the measured characteristics to a second communication device coupled to means for altering the characteristics of the electricity based on the measured characteristics.
In a distribution system for distributing electricity described in CA2784999, devices and methods for decentralized coordinated Volt/VAR control are provided. In the distribution system a load tap changing transformer transforms electricity from a high side voltage provided on a primary side of the load tap transformer to a low side voltage on the secondary side of the load tap transformer. A feeder line is connected to the secondary side of the load tap transformer. A plurality of distribution lines is connected to the feeder line, each by a 2 0 distribution transformer and loads are connected to the distribution lines.
The load tap transformer and a distribution capacitor bank are controlled by an application platform for Volt/VAR control. The application platform for Volt/VAR control determines the control signals based on measurements obtained at the distribution lines, The measurements are transmitted by first communication devices over a network to a network interface (forming a second commnnication device), of the application platform.
For the application platform to work, a network needs to be present besides the electrical distribution system. This requires separate cabling or a claim of radio frequencies. Arranging 3 0 a cabled network from the application platform to the places at the distribution lines where the measurements are obtained, may be costly, for instance to open and close roads or introduces dependency of an electrical power distribution company to a network provider.
Claiming radio frequencies is very cumbersome and often this process is very slow, It is an object of the invention to provide a distribution system for distributing electricity that at least partly solves one or more of these problems.
This object is reached according to a first embodiment of the invention wherein a distribution system for distributing electricity is provided, comprising -a sector arranged to distribute electricity to a plurality of loads over at least one sector power line; -at least one measurement means to measure characteristics of the electricity in the sector; and -a first communication device arranged to send the measured characteristics to a second communication device coupled to means for altering the characteristics of the electricity based on the measured characteristics characterized by the first communication device and the second communication device being arranged to communicate with one another over the at least one sector power line.
Because the first communication device and the second communication device communicate over the sector power lines, this system can be implemented without the need for an external communication network. This decreases the requirements for implementation and facilitates to optimize the distribution to a wider variety of situations.
The means for measuring the characteristics of the electricity may measure voltage, distortion, current, power factor and or flatness of a voltage across the distribution system.
By altering the characteristics of the electricity based on the measured characteristics, the quality of the electricity distributed can be controlled.
The first communication device for sending the measured characteristics to the second 3 0 communication device and the second communication device may be of a type well known to the skilled man to couple signals over a power line, such as those for coupling signals according to an internet protocol over a power line.
Because the first communication device and the second communication device communicate over the sector power lines, this system can be imp'emented without the need for an external communication network. This decreases the requirements for implementation and facilitates to optimize the distribution to a wider variety of situations.
The supply line may be a high voltage line connected to a power generator. The loads may typically be supplied with voltages around nominally 230 V at 50Hz. or 115 Vat 60 Hz, According to EN 50160:2010/AC:2012, the voltage average per 10 minutes should at least be 230 V +10% and -15% and during a one week period the average of the 10 minutes periods should be within 230 V +10% and -10%. The means for allering the characteristics of the electricity typically keep the voltage preferably within 5% of the nominal value, A second embodiment of the invention is provided by a distribution system according to claim 2.
Because electricity can be supplied to the distribution system (I) via the transformer, the voltage in the distribution system (1) can differ from the voltage in the supply line (3).
The supply line may be a high voltage line connected to a power generator.
In a third embodiment of the invention, the distribution system according to the second embodiment is provided, wherein the means for altering the characteristics of the electricity are arranged for altering the characteristics of the electricity at the transformer, By changing the characteristics of the electricity at the transformer, a large loads downstream of the means profit from the changed characteristics.
The means may even be arranged to change the electromagnetic coupling between the primary aM secondary side of the transformer, This may efficiently be done if the means 3 0 comprise a tap changer mechanism for changing the number of windings used in primary or secondary side coils of the transfomier, According to a forth embodiment of the invention, the distribution system according to the second or third embodiment is provided, wherein the second communication device is arranged on the secondary side of the transformer.
Because the second communication device is arranged on the secondary side of the transformer, the signal from the second communication device is minimally affected by characteristics of the transformer including inductance. Therefore, a relatively high signal to noise ratio is achieved or a relatively high communication speed.
According to a fifth embodiment of the invention, the distribution system according to any of the first, second, third or fourth embodiment is provided, wherein the at least one sector power line comprises a feeder arranged for distributing the electricity to a plurality of distribution branches and a first measurement means of the at least one measurement means to measure the characteristics of the electricity arranged at a first distribution branch on of the plurality of distribution branches.
With a plurality of distribution branches to which the feeder distributes electricity, the loads in one distribution branch may influence the characteristics of the electricity in another distribution branch. Because the first means is arranged to measure at the distribution branch, the measurements represent the characteristics as experienced by loads connected to the distribution branch at which it is arranged to a high degree. Therefore, the distribution system can be optimally optimized.
According to a sixth embodiment of the invention, the distribution system according to the fifth embodiment is provided, wherein the distribution branch comprises a distribution transformer and the measurement means measure the characteristics of the electricity are arranged to measure the characteristics of the electricity on the secondary side of the distribution transformer.
Because the measurement means measure the characteristics of the electricity on the secondary side of the distribution transformer, the measured characteristics represent the characteristics of the electricity as experienced by loads connected to the distribution branch well being affected by characteristics of the distribution transformer including inductance similar to how in use loads in that distribution branch are affected.
According to a seventh embodiment of the invention, the distribution system according to the sixth embodiment is provided, wherein the first communication device is coupled to a sector power line of the at least one sector power lines on the primary side of the distribution transformer with a port arranged to communicate with the second communication device.
Because the first communication device is connected to a sector power line on primary side of the distribution transformer with the port and not to the secondary side of the distribution transformer, the signal to noise ratio for the communication signal is high or a relatively high communication speed can be obtained.
Examples of embodiments the invention will now be described with reference to the accompanying schematic drawing. Corresponding reference symbols in the schematic drawing indicate corresponding parts. The schematic drawing is not necessarily to scale and certain features may be exaggerated to better illustrate and explain the present invention.
Further, the examples are not intended to be exhaustive or otherwise limit or restrict the invention to the precise configurations shown in the drawing and disclosed in the following
2 0 detailed description.
Figure 1 depicts a schematic overview of a distribution system according to the invention In a distribution system (1) according to the invention, a substation (2) is used to distribute electricity from a supply line (3) to a plurality of feeders (figure 1). The substation (2) comprises a transformer (4) of the load tap changing transformer type. Such transformers are commonly referred to as LTC transformers. The supply line (3) is a high voltage line carrying an alternating current that is connected to the primary side of the transformer (4). The supply line (3) is also connected to a generator (not shown) arranged to generate a sine wave voltage.
The plurality of feeders is connected in parallel to a secondary side power line (14) on the secondary side of the transformer (4). Each feeder line of the plurality of feeder lines is connected to the secondary side power line (14) by a breaker (5).
A feeder (6) of the plurality of feeders connects a plurality of distribution branches (7) to the supply line (3). Each distribution branch is coupled to the feeder (6). The feeder (6) and the distribution branches (7) connected to the feeder (6) are sector power lines of a sector (13).
The distribution branches distribute the electricity to loads (9) such as the combined load formed by a building, The loads (9) are connected to a distribution power line (17) connected to the feeder (6) A measurement means (10) is arranged to measure characteristics of the electricity such as the voltage, the distortion of the voltage and DC-component. These means may be of any suitable type known to the skilled person.
The measurement means (10) to measure the characteristics of the electricity comprise an output port and is arranged to provide the measured characteristics at the output port. A first communication device (II) is connected to the output port and arranged to receive the measured characteristics. The first communication device (11) is coupled to the feeder (6) and is arranged to transmit the received measured characteristics over the feeder (6). The received measured characteristics are sent over the feeder (6) according to an internet protocol.
The substation (2) comprises a second communication device (12) coupled to the secondary side power line (N). The second communication device (12) in turn provides the received measured characteristics to an application platform (15) for Volt/VAR optimization.
Depending on the measured characteristics, the application platform (15) may change the settings of the load tap transformer (4) or connect a capacitor bank (16) to the secondary side power line (N). The application platform (15), the load tap transformer (4) and the capacitor (16) work together as means with may change the characteristics of the electricity can optimize various operation parameters such as the power factor, the amplitude of the voltage and distortion. In figure 1, the connections between the means for changing the characteristics of the electricity are not shown, These connections may for example be over separate signal lines or be wireless over a WiFi or bluetooth protocol as the different components typically are close enough together within the substation (2).
The skilled person will appreciate that the above example is only an example according to an embodiment of the invention, The invention may be practised otherwise, For example, the feeder (6) may be directly connected to the secondary side of the transformer (4) without an intermediate secondary side power line (14). Also for example, the number of distribution branches may differ or the number of sectors may differ, Also, the distribution system may comprise a voltage regulator and a transformer instead of a 1 0 load tap changing transformeL Moreover, the distribution system may comprise multiple capacitor banks, for example a capacitor bank within each sector.
In addition, measurement means (10) at different distribution branches may share a single first communication device. In figure, the dotted line indicates that the measurement means (10) of two different sectors use one first communication device (11).
Additionally, there may not be a measurement means (10) at every distribution branch (7) as also indicated in figure 1.
