Technical Field

Background
The series capacitor compensation technology is to connect the capacitor in series to the line to improve the transmission capacity of the line, when the high voltage line is in fault, the metal oxide arrester (MOV) connected in parallel with the capacitor will act immediately and limit the voltage change at both ends of the capacitor, but when the accumulated energy of the MOV can not be dissipated quickly, it will explode and be damaged, therefore a spark gap is connected in parallel at both ends of the MOV, when the fault is found, the spark gap is triggered to act, finally the control system controls the bypass breaker to bypass quickly to protect the capacitor and the MOV. It follows that the trigger means of the spark gap is very important and if not triggered reliably and quickly, increases the failure rate of the MOV and capacitor. The series compensation device generally comprises a high-voltage platform and a series compensation chamber, wherein a series capacitor, a metal oxide arrester MOV, a spark Gap, a bypass breaker and a Gap Triggering device (Gap Triggering Electronic-GTE) are arranged on the high-voltage platform, and a control protection device is arranged in the series compensation chamber, wherein the spark Gap is a backup protection for the MOV and the series capacitor, so that high requirements are made on the working reliability and the continuity of the series compensation device.
Series compensation is also called a series compensation device, namely a capacitor bank is connected into a power transmission line in series. The series compensation technology and the high-voltage direct-current transmission technology belong to one of the FACT (flexible power transmission technology), and are increasingly adopted in China due to the characteristics of small investment, quick response, high performance and convenience in maintenance, particularly in large-scale power grids with large span and wide area.

The series capacitance compensation device is used as primary equipment independent of a power transmission line and is provided with a special series compensation protection device so as to realize real-time monitoring and protection of a series compensation capacitor, an MOV, a discharge gap, a series compensation platform and the like. The series compensation protection device is different from other primary equipment protection devices and has the following characteristics: 1) the principle of the series compensation protection device is greatly different from that of other primary equipment protection devices. 2) The analog quantity acquisition loop is many, and the protect function is many. 3) The action result similarity of the series compensation protection device is high.
