This research aims at reducing the inference time and making the solution more accurate and more reliable in power system control problem by using parallel decentralized processing techniques in knowledge engineering. The following results are obtained from this study :(a) A new type of overload refief control system is developed on a McIntosh computer using object-oriented knowledge representation. Performances of the proposed system taking into account parallel processing are tested by using centralized, distributed and hierarchical problem solving techniques respectively. Here, load flow calculation is also excuted in parallel, which leads to a large reduction of the total processing time required for problem solving in a large-scale power system. It is made clear from the comparison of dwe problem solving techniques that there exists the optimal number of subsystems into which the whole system is divided and that hierarchical problem solving system is superior to distributed proble … More m solving system. In addition, it should be noted that the communication time among local processors belonging to subsytems plays an important role in determining the decomposition pattern of the large-scale system.(b) An assisting system for fault section estimation is developed on a McIntosh computer using Common Lisp language. The proposed assisting system uses cause-effect network which is developed here and operating time information of actuated relays and tripped circuit breakers for inference. Taking into account parallel processing, the proposed system makes the very rapid and correct fault section estimation possible compared with the conventional rule-based production system. Furthermore, it makes the proposed system robust to taking necessary countermeasures against erroneous or missing information of relays and circuit breakers. In addition, the use of Petri-net instead of cause-effect network is also investigated to improve the parallelism of inference and good results are obtained. Less

本研究旨在利用知识工程中的并行分散处理技术，减少电力系统控制问题的推理时间，提高求解的准确性和可靠性。研究结果如下：(a)采用面向对象的知识表示方法，在McIntosh计算机上开发了一种新型的过载控制系统。采用集中式、分布式和分层问题求解技术分别对该系统进行了性能测试。在这里，潮流计算也是并行执行的，这使得在大型电力系统中解决问题所需的总处理时间大大减少。从dwe问题求解技术的比较中可以看出，存在将整个系统划分为最优的子系统数量，分层问题求解系统优于分布式问题求解系统。此外，应该注意的是，属于子系统的本地处理器之间的通信时间对确定大系统的分解模式起着重要作用。(b)在McIntosh计算机上使用Common Lisp语言开发了故障段估计辅助系统。本文提出的辅助系统采用本文开发的因果网络，并结合驱动继电器和跳闸断路器的运行时间信息进行推理。与传统的基于规则的生产系统相比，该系统考虑了并行处理，可以实现快速准确的故障区段估计。此外，它使所提出的系统具有鲁棒性，可以针对继电器和断路器的错误或缺失信息采取必要的对策。此外，还研究了使用Petri-net代替因果网络来提高推理的并行性，并取得了良好的效果。少
