Combined with theoretical analysis,this paper presents the implementation methods developed for an on- line transient stability control TSC system.Using real tim e inform ation and on- line calculation,it can generate series of optim al control strategies for contingencies in any given contingency set. The stability calculation method adopts the num erical simulation,which can depict the stability situation of the whole power grid accurately. The generation of the strategy table is based on the algorithm of deciding a suitable fine factor and improved stability integral calculation.When a faultoccurs,the nearest sub- TSC apparatus will match itwith som e strategy in the on- line generated strategy table and execute it. The system not only promises high accuracy,but also m eets the com putational speed requirem ent of on- line transient stability control. The on- line transient stability control system has been tested with thousands of cases in Central China electric network stability monitor and control system and proved significant performance.A sample test is presented in the end of this paper.
