39、 Due to the relative simplicity of the control logic for hydroelectric power plants, the application of computer-based control has lagged, compared to other types of generating stations, such as fossil. Now that computer-based control can be implemented for comparable costs as relay- based logic and
40、 can incorporate additional features, it is being applied in hydroelectric power stations worldwide, both in new installations and in the rehabilitation of older plants.

41、DROELECTRIC POWER PLANT AUTOMATION GUIDE FOR COMPUTER-BASED CONTROL 1 Overview 1.1 Scope This standard sets down guidelines for the application, design concepts, and implementation of computer-based control systems for hydroelectric plant automation. It addresses functional capabilities, performance
42、 requirements, interface requirements, hardware considerations, and operator training. It includes recommendations for system testing and acceptance. Finally, case studies of actual computer-based automatic control applications are presented. The automation of control and data logging functions has
43、relieved the plant operator of these tasks, allowing the operator more time to concentrate on other duties. In many cases, the plants operating costs can be significantly reduced by automation (primarily via staff reduction) while still maintaining a high level of unit control reliability. Automatic
44、 control systems for hydroelectric units based on electromechanical relay logic have been in general use for a number of years and, in fact, were considered standard practice for the industry. Within the last decade, microprocessor-based controllers have become available that are suitable for operat
45、ion in a power plant environment. These computer-based systems have been applied for data logging, alarm monitoring, and unit and plant control. Advantages of computer-based control include use of graphical user interfaces, the incorporation of sequence of events and trending into the control system
46、, the incorporation of artificial intelligence and expert system capabilities, and reduced plant life cycle cost. 1.2 Purpose This standard is directed to the practicing engineer who has some familiarity with computer- based control systems and who is designing or implementing hydroelectric unit or
47、plant control systems, either in a new project or as a retrofit to an existing one. This standard assumes that the control system logic has already been defined; therefore, its development is not covered. For information on control sequence logic, the reader is directed to the IEEE guides for contro
