Abstract

The invention discloses a wind-power-generation digital physical hybrid simulation system based on an RTDS and a method thereof. The simulation system can realize pure RTDS wind power generation system simulation and can realize digital physical hybrid RTDS wind power generation system simulation. The system is formed by a pure RTDS wind power generation simulation system and a digital physical hybrid RTDS wind power generation system. The pure RTDS wind power generation simulation system is realized in RTDS RSCAD software. A simulation controller, a main-circuit mathematical model of a wind power generation system and a simulation power grid model are included. The digital physical hybrid RTDS wind power generation simulation system is formed by the RTDS RSCAD software, an interface card and physical equipment. In the invention, through a variety of modes of simulation, the wind power generation system is integrally analyzed; and in a physical platform, performance of a control strategy is tested and debugged, and a control parameter and the control strategy can be corrected in real time so that an important practice basis is provided for a practical engineering design.

Description

technical field [0001] The present invention relates to the technical field of wind power generation system simulation, in particular to an RTDS (Real Time Digital Simulator, real-time digital simulator)-based digital-physical hybrid simulation system and method for wind power generation systems. Background technique [0002] New energy sources such as wind and solar can effectively solve the power supply problems in remote areas or islands far away from the power supply of large power grids, and are of great significance to local economic development and residents' living security. Wind power has been favored for its unique advantages of cleanliness and low cost, and has become an important part of the domestic renewable energy development strategy. However, due to its power generation characteristics different from conventional power sources, the output power fluctuates greatly. Modeling and simulation of wind power generation system has become an important topic in the fi...
