At present, a hydraulic turbine speed regulator is integrated into a large mesh belt load to operate, theoretically, two main operation modes are available, namely an opening mode and a power mode, and the opening mode is a main operation mode in which the domestic speed regulator is applied to practice for a long time. In recent years, partial domestic power plants gradually start to perform power mode transformation and put into power mode, and can be put into operation after tests are required according to requirements of relevant specifications. In consideration of reasons such as test safety, cost, test rule and the like, a static test should be carried out in the test process, and a dynamic test can be carried out under load after the static test is qualified. However, because the unit has no power output before grid connection, the regulating system cannot form a closed-loop system, many static tests cannot be normally performed, and tests are performed directly with loads after type checking is generally performed, so that the test cost and the test risk are increased, and the test items are not comprehensive due to the limitation of the working conditions of dynamic tests. In addition, according to the standard requirements, the water turbine generator set of 50MW or more and the system analysis show that the generator set needing actual measurement should carry out the actual measurement and modeling work of the parameters of the regulating system according to the regulations, and for the model parameter test of the power mode, because static test cannot be carried out, great difficulty and uncertainty are brought to the establishment of the model at the later stage of the test and the parameter checking work. With the increase of power mode investment, there is an urgent need to solve this problem.
Therefore, a water turbine power mode static test simulation tester is needed, the requirements of related static tests in a power mode can be met, a regulating system can simulate load operation according to an actual regulating rule under a static condition, related tests or debugging work can be conveniently carried out in the power mode, and the problem that the static tests cannot be carried out in the power mode is solved.
