Problems solved by technology

[0006] 1) Due to the different reduction ratios on the pitch transmission link in the fan (referred to as the reduction ratio of the pitch transmission chain), it is difficult for the pitch hub in the laboratory to actually verify the performance of all types of pitch systems. The actual verification can only be The performance verification of the pitch control system cannot be performed until the hub design and production department completes the design and processing of the hub, so t...

Abstract

The invention discloses a flexible simulation test method and system of a pitch system. The flexible simulation test method comprises the following steps of stimulating a main control system of the pitch system to be tested; stimulating the external work conditions of the pitch system to be tested; setting the transmission chain reduction ratio of a variable pitch hub for the pitch system to be tested according to a fan model; testing the internal operation conditions of the pitch system to be tested based on the stimulated main control system and external work conditions; obtaining operation data of the pitch system to be tested. According to the flexible simulation test method and system of the pitch system, full-work-condition stimulation tests under different transmission chain reduction ratios can be performed on the pitch system.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a flexible simulation test method and system for a pitch control system. Background technique [0002] The pitch system is an important part of the wind generator (referred to as fan). The pitch system controls the speed of the wind wheel by controlling the angle of the blades, and then controls the output power of the fan, and can make the fan safe through aerodynamic braking. shutdown. For example, the pitch system can automatically adjust the angle between the blades and the wind direction according to the wind speed, so that the wind rotor has a constant speed relative to the fan nacelle; in addition, it can also control the feathering of the blades to be parallel to the wind direction, so as to realize the shutdown of the fan. [0003] The pitch system is installed on the hub of the wind turbine as a whole. Specifically, the outer ring of the pitch bearing (slewing beari...
