Megawatt-grade hydroelectric generation simulation system

Abstract

A megawatt-grade hydroelectric generation simulation system comprises a first 10-kV busbar, an input switch cabinet, a high-voltage frequency converter, an output switch cabinet, a variable-frequency speed regulating asynchronous motor, a torque and rotational speed sensor TN, a synchronous motor, an excitation cabinet, an excitation transformer cabinet, a grid-connected switch cabinet and an operating table. The first 10-kV busbar is sequentially connected with the input switch cabinet, the high-voltage frequency converter, the output switch cabinet, the variable-frequency speed regulating asynchronous motor, the torque and rotational speed sensor TN, the synchronous motor and the grid-connected switch cabinet; the high-voltage frequency converter is further connected with the grid-connected switch cabinet, the excitation transformer cabinet, the excitation cabinet, the torque and rotational speed sensor TN and the operating table; the operating table is further connected with the grid-connected switch cabinet. The megawatt-grade hydroelectric generation simulation system is high in automation degree and expandability, simulates the running characteristics of a hydroelectric generating set through software control and also can be used for simulating the running characteristics of the other electric generation forms such as a gas turbine and a diesel generator through software extension.

Description

technical field [0001] The invention relates to the research field of renewable energy power generation, in particular to a megawatt-level hydropower simulation system. Background technique [0002] In the 21st century, global energy production and consumption continue to grow, and energy shortages and environmental degradation have become global issues that threaten human survival. Countries around the world are actively exploring the future development route of energy transformation, and will develop new energy and renewable energy as a driving force for the future. As the focus of energy transformation, developed countries such as the United States, Europe, and Japan have successively introduced energy development strategies that focus on supporting the development of new energy. [0003] With the strong support of the state, the development of new energy power generation has made remarkable achievements in recent years: as of the end of 2015, my country's wind power inst...
