A present-day power system is operated with high reliability, and it is rare that a blackout extends all over the system. However, considering its influence upon the society, it is prudent to prepare plans for restoring the system swiftly and securely. This paper deals with automatic power supply to loads after a complete blackout of the system. First, taking characteristics of generators, loads, and initial power sources into account, we propose a method of allocating several generators to each load, paralleling them to the system and supplying power to the load in sequence. Secondly, in order to remove imbalance between supply and demand of power, we propose a method of adjusting the amount of supply and generation according to a present imbalance and the sum of past ones. Thirdly, in order to automatically issue orders for start-up, parallel, follow-up, stand-by, and stop of generators, we set several rules for each power station, and make an expert system based on them. Lastly, we apply the expert system to a model power system, and verify that it can restore loads without any trouble for a complete blackout occured at any time of a day, and in any restoration pattern.
