Abstract

The invention provides reactive power series compensation device topological wiring used for a high-voltage and medium-voltage distribution network. The reactive power series compensation device topological wiring comprises a compensation capacitor Cap, a metal oxide voltage dependent resistor FR, a rapid discharge switch KF1 and a rapid bypass switch KF2. The compensation capacitor Cap is connected in series on a power supply line. The metal oxide voltage dependent resistor FR and the compensation capacitor Cap are connected in parallel. The rapid discharge switch KF1 and the rapid bypass switch KF2 are respectively connected in parallel with the compensation capacitor Cap. The beneficial effects are that operation overvoltage and discharge surge of the line can be solved from the perspective of the wiring and the principle, the problems of reducing the rated voltage of a series compensation capacitor and protecting safe operation of a capacitor bank can be effectively solved, real-time operation electrical parameters can be monitored and the wiring has the function of preventing failure of operation of the rapid switch so that construction cost of the series compensation device is enabled to be greatly reduced, the size is reduced, installation sites are flexible and equipment maintenance is simple.

Description

technical field [0001] The invention belongs to the field of power supply line compensation devices, and in particular relates to a topological wiring of a reactive power series compensation device used in a medium-voltage distribution network. Background technique [0002] With the development of the economy and the rapid growth of electricity load, the power grids in remote areas, which account for most of the country's area, are extending to areas without electricity. The low voltage and high voltage fluctuation rate lead to the power supply voltage at the load end far exceeding the quality standards stipulated by the state, which affects the production and life of people in various regions. In order to find the best method and approach to solve the quality problem of long-distance power supply voltage of 110kV and below distribution network, power workers have been exploring and practicing for decades, and many provinces and regions have focused their attention on the th...
