Abstract

The invention discloses a slave controller based on an active module in an active hybrid filter device, and belongs to the technical field of electric reactive power compensation devices. An output end of a signal sampling and conditioning circuit is respectively connected with input ends of an ADC (analog-to-digital converter) sampling and serial port communication unit and a hardware protection circuit, the ADC sampling and serial port communication unit is bidirectionally connected with a CPLD (complex programmable logic device) control and communication unit, an output end of the hardware protection circuit is respectively connected with input ends of the ADC sampling and serial port communication unit and the CPLD control and communication unit, an output end of a power supply and power isolation circuit is respectively connected with input ends of the signal sampling and conditioning circuit, the ADC sampling and serial port communication unit, the hardware protection circuit, the CPLD control and communication unit and an output and state feedback unit, and the CPLD control and communication unit is bidirectionally connected with the output and state feedback unit. The slave controller has the advantages of wide application range, high accuracy, high speed, high anti-jamming capability and the like.

Description

technical field [0001] The invention relates to the technical field of electric reactive power compensation devices. Background technique [0002] With the rapid development of my country's national economy and equipment manufacturing industry, and the continuous improvement of productivity and industrialization levels, various large-scale electrical transmission equipment, large-scale electromechanical equipment, and metallurgical equipment and other high-power equipment have been widely used. What follows is the deteriorating power supply quality of the power grid, the distortion of the grid voltage waveform, the greatly reduced power factor, and the serious harm of harmonics in the public grid, which reduces the power transmission capacity of the power system and continues to plague our production and life. In recent years, the country has vigorously advocated "energy saving and environmental protection, clean electricity", to improve the power factor of the power grid, a...
