A voltage dynamic whole-process control method, medium and device for coordination between network-constructing new energy and dynamic reactive power compensation equipment

Abstract

The application discloses a kind of network construction type new energy and dynamic reactive power compensation equipment coordination voltage dynamic whole process control method, medium and equipment, method includes: acquisition system real-time operation state, direct current external sending power data;Based on voltage sensitivity analysis, quickly identify the most sensitive reactive power regulation node in system to voltage, select reactive power resource regulation object;Real-time sampling voltage amplitude of each node, issue control instruction;Network construction type new energy and dynamic reactive power compensation equipment according to the control instruction allocated respectively, execute transient / steady state differentiation control strategy, carry out transient overvoltage suppression or steady state voltage control;Online refresh the voltage amplitude of node after regulation and control, and carry out voltage safety check.This method coordinates network construction type new energy and dynamic reactive power compensation equipment, runs through "transient-steady state" voltage whole process control, and is controlled by phase switching through transient and steady state voltage, to ensure that the system voltage dynamic whole process safety and stability after large disturbance provides effective way.
