The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.
In an actually used alternating current circuit, due to the access of a nonlinear load, abundant harmonic waves can be generated in a local alternating current circuit in a power distribution network, so that the voltage and the frequency of the power distribution network are changed, and the power quality of the power distribution network is influenced.
Based on the above problems, the present application provides an active power distribution network power quality monitoring apparatus 10 for monitoring power distribution network power supply power in real time during power distribution network power supply.
An active power distribution network power quality monitoring device 10, as shown in fig. 1, includes a detection and analysis module 100 electrically connected to a power distribution network, a data processing module 200 electrically connected to the detection and analysis module 100, and a display module 300 electrically connected to the data processing module 200.
Specifically, the detection and analysis module 100 is electrically connected to the power distribution network. The detection analysis module 100 is configured to obtain power load data in the power distribution network, and process the power load data to obtain a processing result. Wherein the electrical load data may include nonlinear load data in the power distribution network. The nonlinear load data comprises electric heating element load data, lighting device load data, inductance load data, capacitance load data, power electronic device load data and the like in the power distribution network. After the detection and analysis module 100 acquires the nonlinear load data of the power distribution network, a processing result obtained by processing the nonlinear load data should include at least one of a voltage qualification rate, a three-phase voltage unbalance degree, a three-phase current unbalance degree and a harmonic distortion rate of the power distribution network.
The data processing module 200 is a processing control module, and may be specifically a control chip and the like. The data processing module 200 is electrically connected to the detection and analysis module 100, and is configured to send a control signal according to a processing result obtained by the detection and analysis module 100.
The display module 300 is electrically connected to the data processing module 200 to obtain the control signal sent by the data processing module 200 and operate according to the control signal.
More specifically, when the active power distribution network power quality monitoring apparatus 10 is in operation, the detection and analysis module 100 may acquire and process power load data in the power distribution network. After the processing result is obtained by the detection and analysis module 100, the result is transmitted to the data processing module 200. At this time, the data processing module 200 transmits the processing result to the display module 300, and controls the display module 300 to operate and display the processing result.
The power consumption load data of the power distribution network comprises nonlinear load data in the power distribution network. The nonlinear load data comprises electric heating element load data, lighting device load data, inductance load data, capacitance load data, power electronic device load data and the like in the power distribution network. The detection analysis module 100 obtains the nonlinear load data of the power distribution network, and then processes the nonlinear load data to obtain a processing result. The processing result comprises at least one of the voltage qualification rate, the three-phase voltage unbalance degree, the three-phase current unbalance degree and the harmonic distortion rate of the power distribution network.

At this time, the percentage of the total time for the detection and analysis module 100 to obtain the voltage of the circuit in which the nonlinear load is located is the voltage yield. For another example, the detection and analysis module 100 may obtain voltage values of each phase of the three-phase voltage in the circuit where the nonlinear load is located, and then divide the maximum difference value of the three-phase voltage by the average value of the three-phase voltage to obtain the imbalance degree of the three-phase voltage. Similarly, the detection and analysis module 100 may obtain each phase current value of the three-phase current in the circuit where the nonlinear load is located, and then divide the maximum difference value of the three-phase current by the average value of the three-phase current to obtain the imbalance degree of the three-phase current. For example, the detection analysis module 100 can obtain all harmonic content and fundamental wave in the circuit in which the nonlinear load is located. At this time, the percentage of the root mean square value of the total harmonic content relative to the root mean square value of the fundamental wave is the harmonic distortion rate.
