摘要
This paper proposes a new hybrid simulator which interfaces a dynamic phasor (DP) model of a static VAR compensator (SVC) into the conventional transient stability program (TSP). In this hybrid simulator, the electromagnetic transient simulation of SVC is implemented using dynamic phasor model while the transient stability simulation of the external system is carried out using fundamental phasor model. By taking the fundamental and fifth harmonics into consideration, the dynamic phasor model of SVC presented in this paper is a large-signal, time-variant model which can simulate the nonlinear characteristics of SVC with fast execution speed and high accuracy. The use of DP modeling eliminates the problem of phase discontinuity and dc-offset found in conventional TSP-EMTP hybrid simulation. The effectiveness of this approach is validated using the benchmark results obtained by the DCG EMTP software on the 9-bus and New England 39-bus power systems.
