To m eetthe requirement of real- time analysis and em ergency control of power system s,a novel m ethod is proposed to im plem entthe forced real- time com munication in real- tim e control and analysis system for power systems. In this method, the multi- Ethernet topology is adopted in com munication net design,the connectionless UDP protocol is used as com munication protocol,the multim edia tim er and non- blocking m ode is used in software design. The feasibility of forced real- tim e com munication is proved by the tests of real- tim e performance.A large am ount of experiment data shows that the proposed method can satisfy the real- time and reliable demands of power system s.
