摘要
Abstract
The power angle stability of the large area power grid is improved through the HVDC asynchronous connection.But on the side of the sending-end,the DC fault makes the frequency of gird increase,which will cause frequency stabilization problem.The frequency deviation peak is an important index in the study of the power grid frequency stability.The method of calculating the frequency deviation peak based on the rate of the frequency deviation is obtained from the single machine model.Then,the method is expanded to the actual power system and the application of the method in the HVDC additional control and generator-tripping is studied.Finally,a single machine model and Yunnan Power Grid are simulated to verify the method.The results show that the frequency deviation peak method based on frequency deviation rate is accurate and can be applied to the actual power grid,which has the practical value of engineering.关键词
