Abstract

The invention provides a wind power field real-time simulation modelling system and method. The simulation modelling system comprises a simulation subsystem and a wind field control system; the simulation subsystem is electrically connected virtual synchronous generators in the wind field control system and used for constructing a wind power field model and a power grid model and simulating the running state information of the wind power field model and the power grid model; various virtual synchronous generators are used for outputting a regulation instruction for the wind power field according to the real-time acquired running state information of the wind power field model and the power grid model; the simulation subsystem is further used for corresponding regulating the running state of the wind power field model after receiving the regulating instruction. In the system and method provided by the invention, the actual control equipment is directly added into system to test, the full testing can be performed by simulating the actual working condition, the fan development period can be shortened, the testing risk is reduced, the fault rate is reduced, and the development cost issaved.

Description

technical field [0001] The invention relates to the technical field of wind power generation simulation, in particular, the invention relates to a real-time simulation modeling system and method for a wind farm. Background technique [0002] As a clean renewable energy, wind energy plays a positive role in increasing our energy supply, adjusting our country's energy structure and protecting the ecological environment. [0003] With the continuous increase of the penetration rate of new energy generating units, the proportion of new energy generating units in the power system continues to increase, and the status quo of "large-scale centralized access" and "ultra-high voltage long-distance transmission" of wind power has begun to cause "power grid Systemic intractable diseases such as "subsynchronous oscillation" have brought new challenges to the safe, stable and efficient operation of the power system. [0004] Performance testing and evaluation of wind turbines is an impo...
