Research on the Large Disturbance Characteristics of the Pumped Storage Motor with the Time-Stepping FEM Consequently

Abstract:

In recent years, the proportion of pumped storage power station in the power grid is increasing, which has many special advantages. The pumped storage motor has two kinds of working condition of generator and motor, not only can the system regulate the reactive power, but also can modify the power factor of the grid resulting in the reduction of the investment on the reactive-power-compensation equipment. On the other hand, the above system is able to enhance both the stability and the overall efficiency. Pumped storage motor start-stop and working condition switch frequently. The test will be analysis and researched with the Time-stepping FEM Consequently, this paper analyses the large disturbance characteristics of the pumped storage motor.
