Voltage reactive power regulation method for coordinating transformer substation and power distribution network according to examination and evaluation result
2014
The invention relates to a voltage reactive power regulation method for coordinating a transformer substation and a power distribution network according to an examination and evaluation result. The method comprises the steps that firstly, whether the transformer substation and the power distribution network meet a preset examination requirement or not is judged according to voltage reactive power state information of the transformer substation and the power distribution network; then, a preset transformer substation and power distribution network coordinating and control strategy is executed according to the examination and evaluation result of the transformer substation and the power distribution network. According to the method, only voltage reactive power state information of part of equipment in the power distribution network is collected, the running state of the transformer substation and the running state of the power distribution network can be accurately judged through sensitivity calculation, corresponding control can be carried out, the data amount of real-time collection and operation is small, calculating speed is high, the mounting cost and running maintenance cost of collecting and control equipment are low, high practicality is achieved, and application and popularization are facilitated.
