Grounding resistance monitoring system for high-voltage direct-current power transmission system

The grounding resistance monitoring system for the high-voltage direct-current power transmission system is used for monitoring a resistor to be measured, one end of the resistor to be measured is connected with a bus, and the other end is grounded; the system comprises a processor, an upper computer and a display module, wherein the processor is connected with a temperature detection module and a current detection module; the temperature detection module comprises a temperature sensor; the current detection module comprises a current transformer, the temperature sensor and the current transformer transmit collected temperature signals and current signals to the processor respectively, the signal output end of the processor is connected with the display module, and meanwhile the processor transmits the received signals to an upper computer through an IEC61850 protocol. According to the system, the grounding resistor is included in a background monitoring range, the safety coefficient of operation of a transfo
