Hydro-generator simulation tester

The utility model discloses a hydraulic generator simulation tester comprising a PLC controller, a power supply module, a unit rotation speed simulation circuit, a cooling water system simulation circuit, a unit voltage-building simulation circuit and a bearing temperature simulation circuit. Wherein the PLC is connected with the power supply module; the unit rotating speed simulation circuit comprises an aviation plug, and the speed measuring end of the monitoring system is connected to the signal output end of the PLC through the aviation plug. The cooling water system analog circuit comprises at least two aviation plugs and at least two relays, and the analog quantity input end of the monitoring system is correspondingly connected to the analog quantity output end of the PLC through the aviation plugs. The device is used for simulating a water-turbine generator set in a water-free state, and can simulate parameters of a plurality of water-turbine generator sets for measurement and control of a monitoring s
