On-line real-time simulation testing system of wind generating set controller

Abstract

The invention provides an on-line real-time simulation testing system of a wind generating set controller. The on-line real-time testing system comprises the wind generating set controller, a real-time simulation interaction system and a wind generating set system simulation model. The wind generating set controller issues an action instruction to the real-time simulation interaction system. The real-time simulation interaction system converts the received action instruction and transmits the converted action instruction to the wind generation set system simulation model. The wind generating set system simulation model executes the action instruction transmitted by the real-time simulation interaction system, provides a feedback signal needed by the wind generating set controller and feeds the feedback signal back to the wind generating set controller through the real-time simulation interaction system. A communication mode and a hard-wired mode are compatible, and an application platform is provided for kinds of real-time hardware on-line simulation of the wind generating set. The simulation testing system can be used for testing and evaluating operation and protection characteristics of the wind generating set in a laboratory environment, which facilitates rapid experimental verification of a novel control algorithm and a performance improvement scheme.

Description

technical field [0001] The invention relates to a test system, in particular to an online real-time simulation test system for a wind turbine controller. Background technique [0002] Performance testing and evaluation of wind turbines is an important technical means to improve the grid-connected performance of wind turbines. The existing wind turbine performance testing and evaluation methods mainly include: model algorithm simulation, towed platform testing and field testing. Model algorithm simulation is mainly a test method for establishing a model of a wind turbine using simulation software such as Matlab / Simulink, GH Bladed, and PowerFactory, and using the model for simulation analysis. The accuracy of the test results is strongly correlated with the model accuracy. The towed platform test uses the full power of the motor and generator to simulate the actual wind turbine on the towed platform. However, it cannot simulate all the working conditions of the wind turbine...

The towed platform test uses the full power of the motor and generator to simulate the actual wind turbine on the towed platform. However, it cannot simulate all the working conditions of the wind turbine. Performance testing, and its test area is large and the cost is high

On-site testing can fully reflect the real performance of wind turbines. However, due to the randomness and volatility of wind power, the site is significantly affected by the unit itself and the environment. The test cycle is long, costly, and risky, which is not conducive to new control algorithms and performance improvement solutions. Rapid test verification of

[0003] Although the utility model with application number 201120348789.1 provides a hardware-in-the-loop experimental system for testing the main control system of wind turbines, its wind turbine model is relatively simple and cannot reflect the actual electromagnetic state of the wind turbine; in addition, its simulation model Running in a non-real-time system cannot guarantee the real-time requirements of the main control system and the simulation model, which may cause deviations in the test results
