Dynamic wind power generation simulation experiment system

Abstract

The invention discloses a dynamic wind power generation simulation experiment system. Man-machine interaction, blower fan control, parameter setting and information consultation are realized through built-in LABVIEW software in a network control system module; a PLC main control system module is used for receiving information of the system module and controlling operation of the system module; a yawing pitch variation system module is used for carrying out yawing control, pitch distance adjustment, pitch angle acquisition and abnormality protection; a wind mill power generation system simulation module is used for carrying out wind speed adjustment and rotating speed control; a flow variation system module is used for carrying out electric power transformation, power control, torque control and power factor adjustment; a detection system module is used for carrying out digital quantity acquisition and analog quantity acquisition, a safety protection system module is used for realizing strong wind protection, parameter off-limit protection, voltage current protection, start and shutdown protection and emergency shutdown protection for a set, and a touch screen module is used for realizing real-time display of hand-operated input command and information. The dynamic wind power generation simulation experiment system is convenient to operate and further has an advantage of excellent performance.

Description

technical field [0001] The invention belongs to the technical field of new energy research, and in particular relates to a dynamic simulation experiment system for wind power generation. Background technique [0002] The current mainstream wind power generation systems include: variable speed constant frequency direct drive permanent magnet synchronous wind power generation system and variable speed constant frequency double-fed induction (DFIG) wind power generation system.
