Due to the relative simplicity of the control logic for
37、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 can incorporate additional features, it is being applied
38、 in hydroelectric power stations worldwide, both in new installations and in the rehabilitation of older plants. Page5 EN62270:2004 HYDROELECTRIC POWER PLANT AUTOMATION GUIDE FOR COMPUTER-BASED CONTROL 1 Overview 1.1 Scope This standard sets down guidelines for the application, design concepts, and
39、implementation of computer-based control systems for hydroelectric plant automation. It addresses functional capabilities, performance requirements, interface requirements, hardware considerations, and operator training. It includes recommendations for system testing and acceptance. Finally, case st
40、udies of actual computer-based automatic control applications are presented. The automation of control and data logging functions has 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 significa
41、ntly reduced by automation (primarily via staff reduction) while still maintaining a high level of unit control reliability. Automatic 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
42、practice for the industry. Within the last decade, microprocessor-based controllers have become available that are suitable for operation in a power plant environment. These computer-based systems have been applied for data logging, alarm monitoring, and unit and plant control. Advantages of compute
43、r-based control include use of graphical user interfaces, the incorporation of sequence of events and trending into the control system, the incorporation of artificial intelligence and expert system capabilities, and reduced plant life cycle cost. 1.2 Purpose This standard is directed to the practic
44、ing engineer who has some familiarity with computer- based control systems and who is designing or implementing hydroelectric unit or 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; ther
45、efore, its development is not covered. For information on control sequence logic, the reader is directed to the IEEE guides for control of hydroelectric power plants listed in Clause 2 of this standard. 2 Normative references The following referenced documents are indispensable for the application o
