Problems solved by technology

[0002] In the power system, in order to prevent grid waveform distortion, harmonics need to be filtered, and power needs to be balanced. Not only active power must be balanced, but reactive power must also be balanced, because under a certain active power, the smaller the power factor, the lower the power required. The greater the reactive power, the capacity of power supply lines and transformers needs to be increased in order to meet the requirements of power consumption, which not only increases the cost of power supply, but also reduces the utilization rate of equipment, and also increases line losses. The main function of reactive power compensation is Improve power factor to reduce equipment capacity and power loss, stabilize voltage and improve power supply quality
However, in the existing harmonic compensation or reactive power compensation in the power grid, most of them use the compensation of the local power grid with the power consumption unit or the power supply unit as a unit, such as: centralized compensation, decentralized compensation, and local compensation. These traditional compensation The method can only better adapt to one situation, and it is impossible to coordinate harmonic compensation and reactive power compensation at all levels from a global perspective, and there is no power filter control system established in a large area and multiple levels

Abstract

The invention discloses an intelligent power filtering control system and method, and a storage medium. The system comprises a main line state monitoring unit, a plurality of levels of line state monitoring units, a plurality of levels of power filtering compensation units, a display device and operation end equipment which are all connected with a data operation control center. The main line state monitoring unit and the plurality of levels of line state monitoring units monitor line state parameters of respective levels in real time, transmit data to the data operation control center, and output control signals to the power filtering compensation units of the corresponding levels after operation analysis of an internally preset control algorithm and a control strategy to control the filtering and compensation of the power grid of each level, so as to purify and stabilize the power grid of each level, reduce the line loss, and improve the power supply quality. Compared with like systems in the prior art, the system can intelligently monitor the working state of the power grid, and also can adjust the abnormal or bad state of the power grid. And the power grid is optimally controlled to work in an optimal state.
