【摘要】 继电保护的配置、选型与整定,应遵循"强化主保护、简化后备保护"的原则。江西电网220kV系统主保护配置的加强为简化后备保护的配置和整定计算提供了物质基础;江西电网的快速发展也要求对后备保护的整定计算进行简化。本文提出了江西电网220 kV系统简化配置和整定方案,方案在保证电网安全稳定运行的前提下提高了整定计算工作效率,文中还对简化后电网的安全稳定运行提出了建议。更多还原

【Abstract】 Configuration,selection and setting of the relay protection should follow the principle of enhancing primary protection and simplifying back-up protection.Enhanced protection configuration of Jiangxi Grid’s 220 kV system provides basis for simplifying back-up protection and setting calculation.Also,rapid extension of Jiangxi Grid requires simplifying setting calculation of back-up protection.The scheme for simplifying configuration and setting of the 220kV system is presented in the paper.The scheme can improve the setting efficiency.And suggestion for the safety and reliable operation is proposed.更多还原
