EX2100励磁控制 激励器电源背板 IS200EPBPG1A
IS200EPBP Exciter Power Backplane (EPBP)
EX2100励磁控制(EX2100或励磁器)产生励磁电流来控制发电机交流端子电压和/或无功伏安。这是一个完整的静态励磁系统设计的发电机在新的和改造蒸汽,燃气和水轮机。
EX2100硬件分为以下三种机柜:
• 控制柜用于控制,通信和I/O板
• 用于现场闪光和保护电路的辅助机柜,如去励磁和轴电压抑制
• 电源转换柜,用于电源可控硅电池,冷却风扇,直流接触器和交流断开
励磁器的功率变换器由桥式整流器、电阻/电容滤波器配置和控制电路组成。
励磁器是一个灵活的模块化系统,可以组装以提供一系列可用的输出电流和几个级别的系统冗余。这些选项包括来自电位、复合或辅助电源的电源。可以使用单个或多个桥接器、热备份桥接器以及单一或冗余控制。
励磁器的电力来自与发电机端子相连的电势变压器,或来自与辅助母线相连的励磁变压器。发电机线路电流和定子输出电压是对励磁机的主要反馈,直流电压和直流电流是励磁机磁场的受控输出。
该体系结构支持以太网LAN(单位数据高速公路)与GE其他设备的通信,包括用于配置的GE控制系统工具箱(工具箱)、涡轮机控制、LCI静态启动器和HMI(操作界面)
