BS EN 60880-2009核電站.對安全重要的儀器和控制系統(tǒng).形成A類功能的基于計算機系統(tǒng)的軟件問題

This International Standard provides requirements for the software of computer-based I&C systems of nuclear power plants performing functions of safety category A as defined by IEC 61226.According to the definition in IEC 61513, I&C systems of safety class 1 are basically intendedto support category A functions, but may also support functions of lower categories. Howeverthe system requirements are always determined by the functions of the highest category implemented.For software of I&C system performing only category B and C functions in NPP as defined by IEC 61226, requirements and guidance of IEC 62138 are applicable.This standard provides requirements for the purpose of achieving highly reliable software. Itaddresses each stage of software generation and documentation, including requirements specification, design, implementation, verification, validation and operation.The principles applied in developing these requirements include:– best available practices;– top-down design methods;– modularity;– verification of each phase;– clear documentation;– auditable documents;– validation testing.Additional guidance and information on how to comply with the requirements of the main part of this standard is given in Annexes A to I.

BS EN 62270-2004水力發(fā)電站自動化.計算機控制用指南

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 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.\nThe 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 plant's operating costs can be significantly reduced by automation (primarily via staff reduction) while still maintaining a high level of unit control reliability.\nAutomatic 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 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 computer-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.
