课程名称:380KV GIS测试调试 课程概述:本课程介绍了一种名为“半断路器”配置的变电站,该配置由两条主母线和三个电路断路器组成,通常两条主母线同时带电。此配置允许在不中断电路的情况下对电路断路器进行维护,确保了系统的高可靠性。若任一主母线出现故障,也不会导致电路中断。本课程将为您详细讲解沙特阿拉伯一座变电站的运作基础及联锁电路。还将讨论同步电路及其多重同步系统的必要性,以及该变电站所采用的保护哲学和如何向远端变电站发送跳闸指令。 课程主要内容包括: - 半断路器变电站的CT方法 - 双重操作的重要性 - 测试与服务状态下断路器的闭合条件(上部 - 中部 - 下部) - 断路器的联锁机制(上部 - 中部 - 下部) - 弹簧放电电路及其修改方式 - 为何需要多种同步继电器和电路 - 维保状态和服务状态下的DS/ES条件 - Tee保护的跳闸哲学 - 自耦变压器的差动保护哲学 - 线路差动距离保护的哲学 - 从本地端到远端发送和接收跳闸指令 - 母线保护的哲学 - 断路器故障的保护理念 - 极间差异的处理哲学 该课程适合希望深入了解高压GIS变电站操作与维护的电力工程师和技术人员。
The breaker-and-a-half configuration consists of tow main buses , each normally energized ,Electrically connected between the buses are three circuit breakersThe breaker-and-a-half configuration provides for circuit breaker maintenance, since any breaker can be removed from service without interrupting any circuits.Additionally, faults on either of the main buses cause no circuit interruptions. Failure of a circuit breaker results in the loss of two circuits if a common breaker fails and only one circuit if an outside breaker failsBecause of the importance of this type of substations, we have provided you with this course, in which is a detailed explanation of a substation in the Kingdom of Saudi Arabia. We will talk about the most important basics of operation and interlock circuitsWe will talk about synchronization circuits and why there is more than one synchronization system in the substations , Of course, we will talk in detail about the protection philosophies followed in those substations and how to send trip orders to the remote end substations.The points we will talk about in the course:-CT Methods in Breaker and a Half SubstationsThe importance of Double OperationThe Conditions of closing CB in test and service position (upper - central - lower) CBThe Interlock of (upper - central - lower) CBSpring discharge circuit and how can modified itWhy is there more than one relay and circuit for synchronization ?DS/ES conditions for maintenance position and service positionTrip philosophy of Tee protection 87TEE Philosophy of differential protection with auto transformerPhilosophy of line differential distance protectionSend and receive trip from local end to remote endPhilosophy of BusBar Protection Philosophy of circuit breaker failurePhilosophy of pole discrepancy
