This paper presents a detailed description of the implementation of parallel hybrid simulation on a multiprocessor computer. Hybrid simulation incorporates both the detailed device level simulation and system wide functional modelling within an integrated analysis tool. It can simulate very large networks with transient stability (TS) simulator like speed while delivering electromagnetic transients (EMT) simulator like accuracy on key components. Under the parallel mode of operation, the TS and EMT simulators run in parallel on different processors. A parallel interaction protocol, which makes the parallel hybrid simulation possible, has been proposed. If the parallel hybrid simulation runs in real-time speed, it can be interfaced with real control system hardware for detailed study, including the effects of waveform distortion, and mal-operation of switching devices. In the accelerated time mode, it can be used as a system operation tool, offering extended contingency lists (such as mal-operation of power electronic devices) for dynamic security assessment.
