Wind turbine generator (WTG) models for short circuit analysis

随着风力发电在当今电力系统中的应用越来越广泛，分析风力发电机组短路电流贡献对电力系统的合理设计和保护具有重要意义。目前最流行的电力系统分析软件是PSS/E。然而，由于大系统分析的计算要求，PSS/E基于简化的等效电路计算故障电流。这引起了wtg在各种工况下短路分析精度的关注。在这个Engage项目中，CF Power与该大学联系，研究用于短路分析的WTG建模方法，并评估和提高PSS/E中通用WTG模型的准确性。项目的成功完成将提高行业合作伙伴的工程服务能力，从而使其受益。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.
