Abstract

The invention relates to a reset device of a substation protection measurement and control device, specifically a wireless reset device for substation protection signals, including a main controller and a receiving actuator, wherein the main controller includes a first power management unit, a first MCU main control unit, a second An ISM frequency band radio frequency transceiver unit, GSM / CDMA wireless data transmission unit, input and output interface unit; the receiving actuator includes a second power management unit, a second MCU main control unit, a second ISM frequency band radio frequency transceiver unit and an exit relay unit. In order to overcome the difficult construction and poor operability of the existing substation remote signal reset method, the present invention proposes a reset device. The reset device controls the main controller through the remote control dry contact of the public measurement and control panel. The receiving actuator on the protection measurement and control device communicates, and sends an instruction to turn on the reset circuit, thereby resetting the signal of the protection measurement and control device.

Description

technical field [0001] The invention relates to a reset device for a substation protection measurement and control device, in particular to a wireless reset device for a substation protection signal. Background technique [0002] At present, there are two methods for remote reset of substation protection signals. One way is that the manufacturer of the monitoring background and the protection measurement and control device are the same manufacturer, and the measurement and control device has the function of remote reset signal. The two can reset the protection through Ethernet software protocol communication. In fact, at least 80% of substation monitoring backgrounds and protection measurement and control devices are not from the same manufacturer, or although they belong to the same manufacturer, the measurement and control devices do not have the remote reset function; It is realized by laying cables between the measurement and control devices. This method increases the ca...
