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.

随着风力发电在电力系统中的日益普及，分析风力涡轮机发电机（WTG）的短路电流贡献对于正确的电力系统设计和保护非常重要。目前最流行的电力系统分析软件是PSS/E。然而，由于大电力系统分析的计算要求，PSS/E计算故障电流的基础上简化的等效电路。这引起了对风电机组各种工况下短路分析准确性的关注。在这个Engage项目中，CF Power与该大学进行了接触，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。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。
