Testbänk för turbinregulator

The function of a turbine governor is to maintain the grid frequency close to the nominal value, which in the Nordic grid is 50 Hz. This thesis uses a standard turbine governor from Vattenfall AB, which is implemented with a PLC. The turbine governor gives a control signal which controls the guide vane opening and thus the water flow through the turbine. A test bench for the turbine governor was created where the software LabView was used together with special hardware. The software simulates a Francis hydro power turbine, which gives a feedback signal to the turbine governor. Data for the hydro power turbine, used in the simulation, has been taken from an actual power plant. The user of the test bench has the possibility to choose between actions and to change parameters. For example to give start or stop order, or change setpoint. In this thesis has, for example, a change of guide vane opening setpoint, a grid disturbance, and stops of the turbine, been tested. Validation shows that the result agrees reasonably well with the reality. The result leads to the conclusion that it is possible to create a test bench for the turbine governor with the aid of LabView.
