Dynamic real-time simulator for hydraulic turbine generating unit based on programmable computer controller

A dynamic real-time simulator for hydraulic turbine generating unit based on programmable computer controller has been developed. The basic mathematical models of each component of the hydraulic turbine generating unit were analyzed. The hardware configuration and the software implementation of the dynamic real-time simulator were described in detail. With the simulator, the transients of the different operating conditions of the hydraulic turbine generating unit could be calculated and simulated in real-time. The performance of the hydraulic turbine governor could be test and fine-tuned whether developed in the laboratory or installed in the field. The dynamic real-time simulator also can be operated as a training system for new workers of the hydro power plant. Some simulations and field tests have been conduct with a prototype hydraulic turbine governor, and the results indicate that the dynamic real-time simulator has a good performance.
