WIND POWER PLANT NETWORK SWITCH OUTPUT OPTIMIZATION METHOD AND SYSTEM FOR REDUCING KEY SERVICE TIME DELAY

WIPO Patent Application WO/2021/114494

A1

The present invention relates to a wind power plant network switch output optimization method and system for reducing a key service time delay. The method comprises the following steps: 1) determining the priority of a service signal according to the degree of importance of the service signal; 2) setting the length of a service signal frame corresponding to each priority, and shaping the service signal into a plurality of service signal frames with the same length as the service signal frame; and 3) according to the priority of the service signal, performing output control processing on the shaped service signal frames. In the present invention, by optimizing a resource allocation strategy, reducing a time delay and reducing the uncertainty of a time delay jitter, the punctuality and accuracy of end-to-end key service signal flow time delay control of a wind power plant data network are guaranteed, the volatility and randomness of the output power of a wind turbine generator can be dealt with in real time, and the large-scale grid connection and high power generation permeability of wind power are powerfully supported.
