Wind turbine generator (WTG) models for short circuit analysis

随着风力发电在电力系统中的普及率越来越高，分析风力发电机组S的短路电流贡献对于正确的电力系统设计和保护是非常重要的。目前最流行的工业电力系统分析软件是PSS/E，但由于大电力系统分析的计算要求，PSS/E是基于简化的等值电路来计算故障电流。这就引起了人们对风电机组各种工况下短路分析准确性的关注。在这项Engage项目中，CF Power已与华大接洽，研究风电机组短路分析的建模方法，并评估和提高PSS/E中通用风电机组模型的准确性。该项目的成功完成将使行业合作伙伴受益，提高他们的工程服务能力。该项目还将使加拿大公用事业公司受益，以确保在对电力系统影响最小的情况下大规模开发风力发电。

With the increasing penetration of wind power generation in today's power systems, the analysis of wind turbine generator (WTG)'s short circuit current contribution is very important for the proper power system design and protection. Currently the most popular industrial software for power system analysis is PSS/E. However, due to the computation requirements for bulk electric system analysis, PSS/E calculates fault current based on simplified equivalent circuit. This causes a concern on the short circuit analysis accuracy under various working conditions of WTGs. In this Engage project, CF Power has approached the University to research on the modeling methods for WTGs for short circuit analysis and evaluate and improve the accuracy of generic WTG models in PSS/E. Successful completion of the project will benefit the industry partner by improving their engineering service capabilities. The project will also benefit Canadian utility companies to ensure large-scale development of wind power with minimum impact on power systems.
