The main tasks of the auxiliary equipment monitoring center in the hydropower plant are: receiving various control commands and transmitting the control commands to the local control unit through the field bus to complete the real-time control of the auxiliary equipment; receiving the local control unit The various types of information of the auxiliary equipment are processed, printed, displayed, and saved as needed, and the processed information is uploaded to the host of the hydropower monitoring system. Measurement and control objects: mainly oil pump, pressure transmitter, differential pressure transmitter, pressure switch, oil level signal meter and automatic air supply device. In the automatic operation mode, the working oil pump and the standby oil pump are automatically started and stopped according to the pressure in the pressure oil tank. When the pressure in the pressure tank drops to a certain value, the working oil pump is started; when the pressure in the pressure tank continues to drop to a certain value, the standby oil pump is started, an audible alarm and a standby oil pump start and a hydraulic device failure signal are issued; When the pressure in the pressure oil pump tank rises to a certain value, each oil pump is stopped and the standby oil pump start signal is returned. When the oil level in the pressure oil tank rises to the upper limit of the normal working oil level, if the pressure in the pressure oil tank is lower than a certain value, the gas supply solenoid valve is automatically opened and the exhaust solenoid valve is closed, and the pressure oil tank is ventilated and issued. The oil tank proportional misalignment fault signal of the pressure tank; when the oil level in the pressure tank drops to the lower limit of the normal working oil level or the pressure in the pressure tank rises to a certain value, the gas solenoid valve is automatically closed and the exhaust solenoid valve is opened at the same time. Stop the gas supply to the pressure tank and reset the pressure oil tank proportional misalignment fault signal.
