主要产品详情及功能
数字静态励磁机(AVR)：UNITROL 1020是一款全数字静态励磁机。它通过控制励磁机（如果是无刷励磁机，则控制主发电机）的励磁电流来调节同步发电机的输出电压。这确保发电机在负载变化或其他系统干扰的情况下也能保持稳定的电压输出。
目标应用：它通常用于中小型同步发电机，包括水力发电厂、火力发电厂或柴油发电厂使用的发电机，以及工业交流发电机。
主要调节模式：UNITROL 1020支持多种调节模式，以适应不同的运行要求：
自动电压调节(AVR)：主要模式，保持发电机端电压恒定。
功率因数调节(PFR)：控制发电机的无功功率输出。
无功功率调节(MVAR)：与PFR类似，控制无功功率。
手动励磁电流调节(FCR)：根据特定运行需求或在调试期间直接控制励磁电流。
集成保护功能：励磁机包含全面的保护功能，以保护发电机和励磁系统：
过励磁限制(OEL)：防止励磁电流过大造成损坏。
欠励磁限制(UEL)：防止发电机欠励时失步。
转子电流限制：限制流向发电机转子的电流。
定子电流限制：限制流向发电机定子的电流。
伏/赫兹(V/Hz)限制：防止发电机在低频下过磁通。
电压检测丢失保护：电压测量丢失时做出反应。
过压保护：防止端电压过高。
通信功能：它通常包含标准通信接口（例如，通过RS-485的Modbus RTU），以便与更大型的工厂分布式控制系统(DCS)或SCADA系统集成，实现远程监控、控制和诊断。
用户友好界面：该模块通常配备本地人机界面(HMI)，带有显示屏和按钮，可用于本地操作、参数设置和故障指示。
紧凑设计：UNITROL 1020是一款紧凑型装置，适用于空间有限的应用。
可靠性：作为ABB产品，它采用高品质组件和坚固耐用的设计理念，确保在严苛的工业环境中可靠运行。

Key Product Details and Functions
Digital Static Exciter(AVR):The UNITROL 1020 is a fully digital static exciter.It regulates the output voltage of a synchronous generator by controlling the field current of the exciter(or the main generator if it’s a brushless exciter type).This ensures the generator maintains a stable voltage output despite changes in load or other system disturbances.
Target Application:It’s typically used for small and medium-sized synchronous generators,including those used in hydroelectric,thermal,or diesel power plants,as well as industrial alternators.
Key Regulation Modes:The UNITROL 1020 supports various regulation modes to adapt to different operational requirements:
Automatic Voltage Regulation(AVR):The primary mode,maintaining constant generator terminal voltage.
Power Factor Regulation(PFR):Controlling the generator’s reactive power output.
Reactive Power Regulation(MVAR):Similar to PFR,controlling reactive power.
Manual Field Current Regulation(FCR):Directly controlling the field current for specific operational needs or during commissioning.
Integrated Protection Functions:The exciter includes comprehensive protection features to safeguard the generator and the excitation system:
Overexcitation limitation(OEL):Prevents damage due to excessive field current.
Underexcitation limitation(UEL):Prevents loss of synchronism when the generator is underexcited.
Rotor current limitation:Limits current to the generator rotor.
Stator current limitation:Limits current to the generator stator.
Volts per Hertz(V/Hz)limitation:Protects the generator from over-fluxing at low frequencies.
Loss of sensing voltage protection:Reacts if the voltage measurement is lost.
Overvoltage protection:Protects against excessive terminal voltage.
Communication Capabilities:It often includes standard communication interfaces(e.g.,Modbus RTU via RS-485)to allow integration with a larger plant Distributed Control System(DCS)or SCADA system for remote monitoring,control,and diagnostics.
User-Friendly Interface:The module typically features a local Human-Machine Interface(HMI)with a display and pushbuttons for local operation,parameter setting,and fault indication.
Compact Design:The UNITROL 1020 is a compact unit,making it suitable for applications where space is limited.
Reliability:As an ABB product,it is built with high-quality components and robust design principles to ensure reliable operation in demanding industrial environments.
