A computer program has been written for the simulation of power system transients in real time. The program is based on EMTP models and solution techniques optimized for maximum performance in superscalar computer architectures. Timings ranging from 38 to 107 ps have been obtained for systems from 18 to 30 nodes using an JBM RISC System/6000 Model 560 workstation. These timings are considered adequate for real-time testing of protective relaying equipment. The program is compatible with existing E M " data cases.

“…Another algorithm which uses the same solution method to solve the dynamic security assessment problem, but has a different task partitioning scheme, can be compared to the algorithm in [22] with respect to the work distribution among the processors, the maximum individual processor loading, the amount of information each processor needs from the others, etc.…”

EMS design has traditionally been a top-down process, in which a single vendor provides the algorithms, software and hardware to meet the utility's functional specifications. Recent trends in power systems, such as the move by utilities to Open Systems architectures, and the development of distributed computing systems indicate that this process must be changed to incorporate the new expertise required in EMS design. We propose an Open Design Approach to accomplish this. Our design approach is based on decomposing the EMS design problem according to different levels of abstraction. We define the components of this decomposition and discuss their relationships. These components form the conceptual design for a CAD simulation package which is being developed at UC Berkeley to evaluate and compare the performance of alternative designs.

“…The main idea of the parallel-in-space is to solve the linear equations in parallel and is suitable for parallelizing the serial program [2][3][4][5][6]. Actually it has not fully taken use of the inherent parallel characteristic of power system, for an example: the operation and management of power system is always divided by sub-areas and layers (voltage levels) and exist much parallel behavior among them.…”

Parallel time domain simulation is one of the reliable and potential methods that might realize the real-time online transient stability analysis of power system. In the paper, a new parallel calculation method, based on waveform relaxation method, is proposed for power system transient stability analysis. In the method, the entire transmission network is first divided into several subsystems by the geographical location; for each subsystem, its neighboring systems are represented as equivalent voltage sources at the boundary buses; the tie line flows are considered as the communication waveform among the subsystems; then, time domain simulation for each subsystem is performed in parallel. The test result of the practical system indicates that the new parallel algorithm completely achieves the on-line real-time or even over-real-time calculation speed and could be applied to the on-line transient stability analysis of practical system.
