High-voltage thyristor voltage monitoring board detection device and detection method

Abstract

The invention relates to a high-voltage thyristor voltage monitoring (TVM) board detection device and detection method which are used for detecting the performance of a high-voltage thyristor voltage monitoring (TVM) board. The detection device comprises an EMI filtering circuit, a controllable high-voltage direct-current power source, a controllable low-voltage alternating-current power source, an auxiliary power source, an optical fiber receiver, a wireless module, a display screen and an embedded processor; and the embedded processor controls the EMI filtering circuit to filter mains supply, acquires related voltage and current signals, inputs filtered mains supply signals to the high-voltage thyristor voltage monitoring board, analyzes and compares obtained high-voltage thyristor voltage monitoring board signals and the acquired voltage and current signals so as to obtain the operating state of the high-voltage thyristor voltage monitoring board and transmits the state to a near end client and a distant end man-machine interface through the display screen and the wireless module. The high-voltage thyristor voltage monitoring board detection device and detection method of the invention can independently detect the performance of the TVM board, and judge and locate a fault.

Description

technical field [0001] The invention relates to a device and method for detecting and checking whether a high-voltage thyristor voltage monitoring board (Thyristor Voltage Monitoring Board, hereinafter referred to as TVM board) is working normally. It provides maintenance technical solution support for power grid companies when performing TVM board maintenance, and belongs to electrical equipment. Operation and maintenance technical field. Background technique [0002] UHVDC converters and large-capacity static var compensation devices widely use high-voltage thyristor valves as their basic converter units. Thyristor valves are converter units composed of thyristors connected in series and in parallel. Each thyristor is safe and reliable And the consistency of the trigger signal will affect the working stability of the thyristor valve. Therefore, in the converter valve composed of high-voltage thyristors, each thyristor is equipped with a TVM board. The TVM board provides i...
