Description
Technical field
The utility model relates to a kind of multi-functional hydrogovernor performance testing device.
Background technology
Hydrogovernor is the important opertaing device of hydrogenerator, will carry out the test of Static and dynamic (emulation) before unit puts into operation to speed regulator system.
Existing test device for governor of hydraulic turbine, usually can only send to the frequency signal of fixed step size, therefore can only the static properties of single test speed regulator system, realize the simple computation of several parameter such as record ripple and controlling dead error of the signal such as guide vane opening, frequency, owing to lacking the assistance of local control unit, other external variables of unit cannot input, and operating condition of test can not automatically switch, emulator is not high, is unfavorable for the precision and the reliability that ensure test result.Existing test device for governor of hydraulic turbine is owing to can not provide the power of the assembling unit, water level signal in addition, cannot be suitable for the unit and the pump-storage generator that need water level signal to calculate blade and guide vane opening joint.
Realistic model is set up according to the variation relation of unit operation when different operating mode between guide vane opening and the signal such as the power of the assembling unit, frequency, the signals such as real-time transmitted power, frequency, water level are to governor control system, sent the start order of unit operation by simulation local control unit simultaneously, the orders such as oil switch, coordinate speed regulator system to set up and highly emulate operating mode, adopt high-frequency acquisition module to complete the Real-time Collection of speed regulator service data.So just can carry out operating mode emulation to dissimilar machine unit speed regulating device system, in anhydrous conditions the dynamic and static performance of speed regulator reliably be tested, just can break the restriction of site test environment, shorten the test period.
Summary of the invention
The utility model provides a kind of multi-functional test device for governor of hydraulic turbine, can carry out Static and dynamic performance test in anhydrous conditions to the speed regulator of dissimilar unit.
