| Abstract:This paper looks into the high frequency risk existing in Northwest Power Grid and the dispatching management situation of safety automatic device incorporated in defense line of high frequency cutting generator. The software and hardware framework of integrated monitoring and early warning system for defense line of high frequency cutting generator in regional and provincial two-level dispatching center is designed starting from the practical application requirements of ensuring the frequency security of the large sending end power grid. The paper describes several key technologies for implementing the system， including high frequency cutting generator information exchange based on service bus， general modeling of high frequency cutting generator strategy， total quantity statistics of high frequency available cutting generator power. Finally， the application of the system in Northwest power grid is introduced. Trial operation results show the system software can automatically combine the strategy model of the high frequency cutting generator and the actual running state of the safety automatic device， achieve accurate statistics of each round total power of high frequency cutting generator in each regional power grid.When the any round total power of high frequency cutting generator in any region exceeds the limit， the dispatcher can be alerted in time. |
