Automatic Control in Power Generation, Distribution, and Protection covers the proceedings of the IFAC Symposium, held in Pretoria, Republic of South Africa on September 15-19, 1980. The book focuses on the methodologies, technologies, processes, and approaches involved in the adoption of automatic control in power generation, distribution, and protection. The selection first elaborates on decentralized and centralized automatic generation control; digital control methods for power station plants based on identified process models; and power generating unit mechanical and electrical system interaction during power system operating disturbances. The text then ponders on modern trends in power system protection; control of power generation and system control with emphasis on modern control theory; and electronics in future power systems. The manuscript takes a look at a specification for an operator load flow program in an energy management system; minimum MVAR generation as an effective criterion for reactive power dispatching; and influence of inaccurate input data on optimal short-term operation of power generation systems. The secondary voltage control of EDF network, directional protection for digital processor use, and securing high availability of protection relays and systems are also discussed. The selection is a dependable reference for readers interested in the application of automatic control in power generation, distribution, and protection.
