晶闸管支路过载
这可以防止由于不对称电流导致的单个晶闸管支路过载，并显著降低单个功率转换器故障的概率 带励磁电流调节器的电压调节器（AUTO），除了电压调节器（AUTO）和励磁电流调节器（MAN）外，还可以使用独立的电流调节器。由于对所有非活动调节器的跟踪控制，在活动调节器发生故障的情况下，可以保证平稳切换到准备运行的调节器通道。标准程序的结构良好的软件已经提供了大部分调节，励磁系统安全运行所需的保护和监控功能，以及用于诊断和服务的综合事件和数据记录。第4页标准程序的功能这包括以下励磁特定功能：调节器功能带PID滤波器的电压调节器（自动操作模式）带PI滤波器的励磁电流调节器（手动操作模式）？无功负载和/或有功负载下降/补偿限流器：–最大和最小励磁电流–最大定子电流（超前/滞后）–P/Q欠励磁–伏特/赫兹特性后续控制–通道1↔ 通道2（用于双自动通道系统）–活动通道↔ 备用（对于带备用调节器的系统）–操作模式自动↔ MAN功率因数/无功负载调节手动限制电力系统稳定器（可选）–符合IEEE-PSS2A–自适应电力系统稳定剂–多频带电力系统稳定。

Thyristor branch overload
This can prevent overload of a single thyristor branch due to asymmetric current, and significantly reduce the probability of failure of a single power converter. In addition to the voltage regulator (AUTO) and the excitation current regulator (MAN), independent current regulators can also be used. Due to the tracking control of all inactive regulators, in the event of a failure of the active regulator, it can ensure a smooth switch to the regulator channel ready for operation. The well structured software of the standard program has provided most of the regulation, protection and monitoring functions required for the safe operation of the excitation system, as well as comprehensive event and data recording for diagnosis and service. The functions of the standard program on page 4 include the following excitation specific functions: regulator function voltage regulator with PID filter (automatic operation mode) excitation current regulator with PI filter (manual operation mode)? Reactive load and/or active load drop/compensation current limiter: – maximum and minimum excitation current – maximum stator current (lead/lag) – P/Q underexcitation – subsequent control of volt/hertz characteristics – channel 1 ↔ Channel 2 (for dual automatic channel system) – active channel ↔ Standby (for systems with standby regulators) – operating mode automatic ↔ MAN power factor/reactive load regulation manual limiting power system stabilizer (optional) – compliant with IEEE-PSS2A – adaptive power system stabilizer – multi band power system stability.
Protection and monitoring functions
Magnetic field flicker time overcurrent protection (instantaneous/inverse time limit) per Hz voltage protection loss of excitation protection power converter temperature rotor temperature rotating diode monitoring thyristor conduction monitoring power converter fuse monitoring power converter fan monitoring measurement circuit monitoring. The monitoring and protection functions are divided into three different action levels: only the fault display is switched to the second channel or the standby regulator (if provided) or the instantaneous excitation trip for protection purposes is redundant using the available power converter. Control functions All standard excitation sequences and interlocks are software based with fixed pre programmed function blocks. Users can extend them through freely programmed function blocks. The data recording UNITROL 5000 software has an event recorder (fault recorder), which can record up to 100 events and alarms with real-time markers. Use the control panel or CMT software to read and analyze logs. The data recorder (Datalogger) can record up to six measurement signals in real time. These can be displayed graphically in the CMT software trend window for diagnostic purposes. After the monitoring processor self-test power is turned on, the processor starts self-test. The processor also monitors various power supply voltages. The program execution monitoring processor card has an internal watchdog function to monitor the correct execution of the program.
