Study on Comprehensive Evaluation Model of Wind Farm Operation Performances Based on the Multi-level Fuzzy Method

In order to evaluate comprehensively and objectively the safety performance of the grid connected wind farms, a comprehensive evaluation index system is built, and multilayer fuzzy synthesis evaluation method is used to evaluate the grid connected wind farm operation safety. Firstly, a judgment matrix is built to determine the weight of each index, Then, according to the fuzzy boundary tectonic membership description of each factor and factor fuzzy evaluation matrix, Finally, through the composite operation of multi-layer evaluation object belongs to grade fuzzy behavior index and membership function, Implementation of the system, on the performance of grid connected wind farm, a comprehensive evaluation of the quantitative and the relative ranking of wind farm. In the example analysis, the comprehensive evaluation of three typical wind farm to verify the effectiveness and feasibility of the method.
