LCT微机励磁控制器 操作说明书 LCT Digital Excitation Controller User’s Guide 3、控制器的基本操作 Basic Operation of the Controller:
控制器的基本操作是针对控制器的状态而言,并非针对液晶显示器。有关液晶显示器的操作详见第4、5章。Controller’s basic operation is aim at controller’s state, not LCD. The operation about LCD is in chapter 4 and 5.
3.1 控制器的控制 Control the Controller：
根据面板上的布置, 控制器的控制主要由“主控”/“就地”开关控制。According to the collocation of faceboard, the controller is controlled by “REMOTE”/ “LOCAL” breaker.
当“主控”/“就地”开关置于“就地”时,面板上的“运行”/“退出”开关、“置位”、“增磁”、“减磁”按钮起作用。当“主控”/“就地”开关置于“主控”时,上述面板开关按钮不起作用,控制器受控于中控输入开关量，通过DI1（运行/退出）、DI3（增磁）、DI4（减磁）、DI7（起励）起作用。When “REMOTE”/ “LOCAL” breaker parks “LOCAL”, “RUN”/ “QUIT”breaker, “EXC-S ON”, “RAISE”, “LOWER”button on the faceboard will work. When “REMOTE”/ “LOCAL” breaker parks “REMOTE”, the above faceboard breaker won’t work, controller will be controlled by remote digital input data, work by DIL(run/quit), DI3(raise excitation), DI4(lower excitation), DI7(state excitation).
说明:“起励”、“置位”的含义是一致的,即针对非自并励机组,该开关量或按钮仅仅是“置位”的含义,将发电机电压快速升至要求的电压。自并励机组,该开关量或按钮实际上是起着“起励”＋“置位”的作用,即先启动“起励”按钮让发电机建立电压,然后将发电机快速升至要求的电压。“置位”或“起励”在发电机空载状态上,发电机电压低于“置位”时所达到的电压值下才有效。Explaination: The meanings of “state excitation”, “EXC-S ON” is accordant, namely aim at static excitation, the breaker or button only means “EXC-S ON”, rise the generator voltage to need one quickly. static excitation, the breaker or button really works as “state excitation” and “EXC-S ON”,namely start up “state excitation” button first to make generator build voltage, then rise the voltage to need one quickly. When”EXC-S ON” or “state excitation” stays on generator noload state, generator voltage is less than the voltage of “EXC-S ON” building up, it is efficient.
手动运行时按发电机转子电流或调节器输出电流（无刷励磁系统）闭环方式调节。When manual running regulate according to generator rotor current or regulatoroutput current(brushless excitation system) closed loop mode.
3.2 控制器的上电 Power Supplies of the Controller：
控制器在上电前要求各开关量处于退出运行状态,即面板上开关处于“就地”、“退出”位置或者面板上开关处于“中控”位置而输出开关量DI1（运行）处于断开状态。

LCT微机励磁控制器 操作说明书 LCT Digital Excitation Controller User’s Guide Before controller electrifying all digital data must stay on quit running state, namely the breaker of faceboard stays “LOCAL”, “QUIT” location or the breaker of faceboard stays “REMOTE” location while digital output DI1(run) stays on disconnection state.
3.3 控制器的操作 Operate the Controller：
在表一中，“置位”或“起励”有效的条件为发电机处于空载状态（即出口断路器断开）,且发电机电压没有达到“置位”所需达到的电压。In the table one, the condition to make “EXC-S ON” or “state excitation” effective is that generator stays on noload state(namely generator breaker disconnection), and generator voltage hasn’t reached the voltage which is needed to “EXC-S ON”.
在控制器正常情况下控制器状态遵循下表所示:When controller is ok state follow as following table shows: 面板（或面板背面） 输入开关量 Panel(Back of Panel) Digital input 控制器 状态 中控/ 运行自动/ DIDI3 DI4 DI7 State 就地 / 增磁 减磁 置位 1 手动 增磁 减磁 起励 of Raise Lower Set Remot退出 Auto/ 运Raise Lower Set control e/ Run/ ManuaEXC EXC EXC 行 EXC EXC EXC Local Quit l 无效 无效 无效 退出 就地 退出 × × × InvaliInvaliInvali× × Quit Local Quit d d d 自动 就地 运行 自动 有效 有效 有效 × × × × Valid Valid Valid Auto Local Run Auto 手动 手动 无效 就地 运行 有效 有效 × × ManuaInvali× × ManuLocal Run Valid Valid l d al 中控 无效 无效 无效 退出 断 × × × × × RemotInvaliInvaliInvaliOff Quit e d d d 中控 自动 自动 合 有效 有效 有效 × × × × RemotAuto On Valid Valid Valid Auto e 手动 中控 手动 无效 合 有效 有效 × Manua× × × InvaliManuRemotOn Valid Valid e l d al 表一 Table 1 说明：×----无所谓“合”和“断”。explaination：×----“close”and“off” are indifferent.

LCT微机励磁控制器 操作说明书 LCT Digital Excitation Controller User’s Guide 自动运行时当出现故障并切手动后要恢复自动运行，注意 有两种操作模式：一、要将面板打开，将面板背后的“自CAUTION 动/手动”拨码开关置入“手动”位置后,再切至“自动”状态,才能恢复原状；二、待调节器运行状态稳定，观察自 动跟踪到位后，在“运行数据界面”下，参照5.1节操作恢复自动运行。When error hapans during automatism running and after manual cut it needs to renew automatism running，there are two operation modes：one.Open the faceboard,put “automatism/manual” dial code breaker in the “manual” location，then switch to “automatism” state , it will involute; two.After regulator running stably, observe automatic follow reach its location, under “running data menu”, according to chapter 5.1 to renew automatism running. 自动运行时当出现故障并使控制器退出运行时,若“就地”状态,则使面板“运行/退出”开关切置“退出”再切回“自动”即可恢复。若处于“中控”状态,使DI1（运行）开关断开后再合上即可。When error occurs and make controller quit running during automatism running, if “LOCAL” state, then make faceboard “run/quit” breaker switch to “QUIT” then switch back to “automatism” then it will renew. If stays on “REMOTE” state, make DI1(run) breaker off and then close it will be ok. 10
