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 filter control system, method and storage medium. The system includes a main line state monitoring unit connected to a data operation control center, several levels of line state monitoring units, and several levels of power filter compensation units. , display device and operation terminal equipment; the main line state monitoring unit and several levels of line state monitoring units monitor the line state parameters of their respective levels in real time, and transmit the data to the data operation control center, through the internally set control algorithm and control After the calculation and analysis of the strategy, the control signal is output to the power filter compensation unit of the corresponding level, and it is controlled to filter and compensate the power grid of each level, so as to purify and stabilize the power grid of each level, reduce line loss and improve power supply quality. Compared with the prior art, the present invention can not only intelligently monitor the working state of the power grid, but also adjust the abnormal or bad state of the power grid; optimize the control of the power grid to make it work in the best state.
