Embodiment Construction

[0060] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0061]In order to analyze the impact of wind power generation on the dynamic characteristics of the power system, it is necessary to establish a dynamic mathematical model of the wind power generation unit and the wind farm. A wind turbine is a complex system involving multiple disciplines. The working principle of the blade is based on aerodynamics, the working principle of the transmission system involves mechanical theory, the generator realizes electromechanical energy conversion, and the wind power control system extensively involves control theory and electrical principles. Therefore, it is very necessary and useful to carry out experimental verification after ...

Abstract

The invention discloses a static testing and calibrating method for a PID link of a control system of a wind turbine generator. The static testing and calibrating method mainly comprises the steps of testing a PID control link, testing the PID adjusting response characteristics, and carrying out specific experiments based on the testing results of the PID control link and the testing results of the PID adjusting response characteristics. The static testing and calibrating method for the PID link of the control system of the wind turbine generator can overcome the defects of being inconvenient to test and low in testing accuracy in the prior art and has the advantages of achieving the purposes of being convenient to test and high in testing accuracy.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a static testing and verification method for a PID link of a wind turbine control system. Background technique [0002] With the grid connection of large-scale wind turbines and wind farms, new challenges have been brought to grid planning and operation. In particular, the operating characteristics of wind power bases that are far away from the load center and have huge capacity will inevitably have a significant impact on the stable operation of the power grid. [0003] In order to meet the challenges and solve the problems of safe, stable and economical operation of the power grid when the wind farm is connected to the grid, the power grid needs to implement advanced technology and management measures, and these are inseparable from the simulation research of the power system including wind turbines and wind farms. Research on mathematical models and accurate par...
