Description

Wind turbine generator gas-turbine electric control full-dynamic joint simulation method and system Technical Field The application relates to the technical field of new energy power generation, in particular to a wind turbine generator gas-turbine electric control full-dynamic joint simulation method and system. Background In order to fully simulate the dynamic characteristics of the wind turbine generator, it is important to construct a related computer simulation platform. The wind turbine generator comprises at least pneumatic, mechanical, control, electric and other links, and the current mainstream wind turbine generator simulation software mainly focuses on pneumatic and mechanical parts (such as Bladed, openFAST software recognized in the industry), and the control and electric part modeling is generally simpler. However, with further development of wind power generation technology, control and electrical links of the wind turbine generator become more and more important, for example, a control system is generally used for wake optimization and damping mechanical oscillation, and an electrical system interacts with a power grid through a power electronic converter, so that multiple functions of inertia extraction, load shedding, frequency modulation, fault ride-through and the like exist. However, the refined model of the control and electrical parts is often emulated in another software (e.g. Simulink software), which greatly simplifies the mechanical and pneumatic parts. It can be seen that in the current technology, different physical dynamics of the wind turbine generator are simulated by different software respectively, and although the simulation software can adapt to a general scene, for a research requirement with a high level (for example, research on the influence of power grid dynamics on mechanical vibration of the wind turbine generator), the current simulation software platform cannot provide a solution well, and a special joint simulation platform is required to simulate multiple physical dynamics simultaneously so as to solve the current requirement. In this regard, there are some related technical solutions at present, which implement "gas-machine-electric-control" joint simulation by the following mechanisms, respectively: the OpenFAST software generates data in advance through simulation, and then inputs the data into the Simulink; The Simulink software calls OpenFAST software through a program interface in each step; OpenFAST is combined with RTDS by calling in real time in a Linux system. In the technical scheme disclosed in the publication, the first scheme is not combined simulation, the signal of Simulink is not transmitted back to OpenFAST as a regulating quantity, the influence of electric control dynamics on gas engine dynamics cannot be reflected, the OpenFAST of the second scheme is not independently operated, the expandability is weak, the compiling is difficult to be carried out into independent program operation, and the third technology is required to depend on a real-time simulation platform RTDS, is relatively high in price and cannot be used at low cost.
