Problems solved by technology

On the contrary, if it is improperly selected or used, it may cause many factors such as power supply system, voltage fluctuation, harmonic increase, etc.
[0003] However, due to the huge power grid system, the types and distribution of reactive power are extremely complex, which poses a great problem to the reactive power compensation of the power grid. At present, it is necessary to quickly make different reactive power compensation measures for different situations. make improvements

Abstract

The invention relates to the field of electrical equipment, and particularly discloses a reactive compensation method, which comprises the following steps of: acquiring power grid data, and collecting and synthesizing the acquired data; analyzing the integrated data to obtain reactive data; performing classifying according to the reactive power data, and controlling the reactive power compensator to work; and carrying out closed-loop detection on the power factor of the power grid after reactive compensation. The method has the advantage that the reactive power compensator of the corresponding type can be quickly started according to different types of reactive power.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a reactive power compensation method. Background technique [0002] Reactive power compensation, the full name of reactive power compensation, is a technology that plays a role in improving the power factor of the power grid in the power supply system, reducing the loss of power supply transformers and transmission lines, improving power supply efficiency, and improving the power supply environment. Therefore, the reactive power compensation device is in an indispensable and very important position in the power supply system. Reasonable selection of compensation devices can minimize the loss of the power grid and improve the quality of the power grid. On the contrary, if it is improperly selected or used, it may cause many factors such as power supply system, voltage fluctuation, and harmonic increase. [0003] However, due to the huge power grid system, the types and distri...
