The invention proposes a
system simulation method for connecting large-scale
wind power into a
power grid in a centralization way and an effective equivalent mode of a high-capacity
wind power station. Based on the synchronization operating characteristics of the large-scale
wind power, the invention makes the large-scale wind power synchronization
simulation analysis principle under the comprehensive consideration of the influences of the
wind resource characteristics of
wind power generation, the dynamic
response characteristics of a
wind driven generator and the differentiation characteristics of different types and different control
modes of various
wind driven generators and the like; therefore, the invention constructs the complete analytical framework and flows of the
system simulation assessment with the large-scale wind power being connected into the
power grid. The simulation analysis result shows that the
system simulation method can comprehensively, objectively and accurately assess the
impact and the safety
bottleneck to the stable running of a power system caused by wind power synchronization after the base synchronization of the large-scale wind power due to the affection to the dynamic
response characteristics of the power system by the differentiation of the types and the
response characteristics of various
wind driven generators and the
wind resource characteristics. Therefore, the method is beneficial for the scheduling and operating staff to accurately grasp the affection to the
system characteristics by the connection of the large-scale wind power and the law of the connection of the large-scale wind power, and has significant meaning for instructing and making the corresponding precautionary and improved measure and ensuring the normal running of the system after the connection of wind power.
