Abstract

The present invention relates to a reactive power compensation controller and a redundant compensation design method thereof. In the present invention, a plurality of compensation modules are provided, including a static var compensator group and a static synchronous compensator group; the control module is also provided with The DSP control module, the static var compensator group and the static synchronous compensator group are connected to the DSP control module through a Modbus bus module. The above technical solution improves the working efficiency of the compensation system and reduces losses; ensures that the system has a strong ability to cope with sudden changes, has faster dynamic response speed, higher reliability, longer service life, more stable system, and simple system construction; Promote the technical level of dynamic reactive power compensation and promote the construction of smart grid.

Description

technical field [0001] The invention relates to the field of power quality management, relates to the design of a hybrid reactive power compensation controller in reactive power compensation technology, and in particular to a reactive power compensation controller and a redundant compensation control method thereof. Background technique [0002] With the development of science and technology, more and more users have adopted high-tech equipment with good performance and high efficiency, but are sensitive to changes in power characteristics, causing the power load to increase continuously; the increasing power load has caused a huge impact on the power grid , so that the power quality of the power grid deteriorates, which brings great pressure to the power quality control. In this context, there is an urgent need to increase the corresponding reactive power compensation device in the power grid to compensate the reactive power consumed by the load, improve the power factor, a...
