Problems solved by technology

[0002] At present, the on-duty mode of the substation is an unattended substation. The operation of the power grid is highly dependent on the remote communication screen in the main control room and other secondary protection devices for station-side communication. In the actual work process, the secondary protection device will crash after running for a long time , causing communication interruption in the substation, the monitoring department cannot monitor the situation in the station. At this time, the operation and maintenance personnel need to start from the station to go to the communication interruption power station to reset the signal. Due to the large number of secondary equipment, abnormal signals are frequently generated, which aggravates the operation and maintenance personnel. workload

Abstract

The invention discloses a substation telecontrol signal power failure reset device and system; the output circuit of the relay JDQ is used to connect in series with the main power circuit of the equipment to be reset in the substation site through two empty nodes of each group of signal terminals; the output circuit of the relay JDQ is The configuration is normally closed; the input circuit of the relay JDQ is configured to be controlled by the drive circuit; after the controller receives the time interval of the opening and closing action in the reset control data, it generates the first moment according to the time interval of the opening and closing action. T1 corresponds to the first control signal sent to the drive circuit, and the second control signal corresponds to the first time T2 and sent to the drive circuit. After receiving the first control signal, the drive circuit controls the relay JDQ input loop to be energized, and the drive circuit receives the second After the control signal, the input circuit of the control relay JDQ is powered off; wherein, the time interval between the first moment T1 and the second moment T2 is the same as the time interval between opening and closing actions.

Description

technical field [0001] The invention relates to the field of power grid equipment monitoring, and mainly relates to a power failure reset device and system for a substation telecontrol signal.
