Description

technical field [0001] The invention relates to the field of power distribution and utilization, in particular to a capacitor control module for controlling external capacitors to perform grid reactive power compensation. Background technique [0002] As a dynamic reactive power compensation device, the static var generator is applied in the distribution network of long-distance power transmission, which can dynamically compensate the reactive power of the power grid. When the power grid is inductive, the static var generator will emit capacitive power. Current to offset the opposite reactive current. When the power grid is capacitive, the static var generator will emit inductive current to offset the opposite reactive current, effectively reducing the loss of power supply transformers and transmission circuits, and improving power supply efficiency. , Improve the power supply environment. However, in a complex grid environment, there are many capacitors that need to be con...

Problems solved by technology

However, in a complex grid environment, there are many capacitors that need to be connected to the static var generator. A static var generator cannot meet the compensation requirements of the complex grid environment, and cannot guarantee the improvement effect on the grid environment.

Connecting multiple static var generators to the grid environment will not only increase the cost, but also increase the labor burden, which is time-consuming and labor-intensive
