摘要：
British Columbia Transmission Corporation (BCTC) in its System Control Modernization Project (SCMP) has integrated Powertech Labs' DSATools with Areva's energy management system (EMS) to perform online dynamic security assessment (DSA). The dynamic security of BC's power systems and overloading, voltage limit violation, voltage instability, frequency instability, and transient instability that are maintained by installing extensive remedial action schemes (RAS) or system protection schemes (SPS). The schemes maintains various credible single, double, and even triple contingencies with different kinds of actions involving generation shedding, load shedding, line tripping, and shunt switching. DSA software packages such as DSATools, ETMSP, PSLF and PSSE are not designed to model circuit breakers (CB) in a systematic fashion but CSA are modeled in a systematic fashion in EMS. The quality of a base case generated from EMS for online DSA experienced inaccuracies in state estimation (SE) solutions ruining the time domain simulations.
