中文摘要	A time-domain simulation approach based on parameter-switching tracing (PST) technique is adopted for power system transient stability analysis. With the time-step-size expanded as an unknown variable to be solved, the differential-algebraic-difference equations are solved continuously through two phases of prediction and correction. Based on the PST method, a type of sensitivity from state variable limits and restraint functions to controllable variables, is proposed and formulated. Then a sensitivity based preventive control method for transient stability is proposed. The objective in this control method is to minimize the total cost of control and coordination among multiple contingencies is also considered. At last, the PST method and the sensitivity based preventive control method are validated through digital tests on the New England 10-generator 39-bus system.
