Abstract

The invention provides a controller for a series compensation device, and belongs to the technical field of capacitor compensation. The controller solves the technical problems that the existing controller is single in function, low in control efficiency on the series compensation device and incomprehensive in protection so that the series compensation device is low in reliability and poor in stability. The controller for the series compensation device comprises a main controller, a detection circuit, a switching control circuit and a communication device, wherein the main controller is connected with the detection circuit, the switching control circuit and the communication device; the main controller is arranged outside the series compensation device, and controls the operation of the switching control circuit and the communication device inside the series compensation device according to the detection result of the detection circuit; and the communication device is in communication connection with a control center. The controller is used for operating control of the series compensation device.

Description

technical field [0001] The invention relates to the technical field of capacitor compensation, in particular to a controller of a series compensation device. Background technique [0002] my country's 10kV and 6kV power distribution networks are huge in scale and complex in load conditions, so their operation and power quality are more important. Voltage quality is an important indicator of power quality. From the perspective of engineering practicality, voltage quality refers to the deviation between the actual voltage and the ideal voltage, reflecting whether the power provided by the power supply department to users is qualified. [0003] At present, capacitive compensation devices are often used to adjust the impedance, voltage, phase, power, etc. of the AC transmission system. When the existing capacitor compensation device is used in a system with fast reactive power changes or impact loads, it is usually equipped with protection equipment to achieve flexible control...
