英文摘要：

Distributed transient stability simulation is a new approach for on-line security analysis of large scale power systems.It utilizes the heterogeneous computing resources and overcomes the difficulties in data acquisition,integration and maintenance.In order to prove the feasibility of distributed simulation in large power system on wide-area communication networks,a set of indexes are proposed including accuracy,efficiency,stability,robustness and scalability.A high performance distributed simulation platform is presented, which can not only realize a dedicated decomposition and coordination algorithm but also can simulate the real wide area communication network environment with high latency and limited bandwidth. Two large scale interconnected power systems, the state power grid and the Northeast China-North China-Central China power grid, are used to test the proposed indexes. Test results prove the feasibility of the distributed simulations among dispatch centers.
