描述
WOODWARD 5461-654是伍德沃德（WOODWARD）公司为电力系统及工业自动化领域设计的核心数字控制器，集同步控制、负荷管理与电力参数监测于一体。以下是其核心功能与技术特性：
1.核心功能
同步与负荷控制：
支持作为独立同步器或同步器+负荷控制器使用，可实现发电机并网时的频率、相位匹配及电压调节，并通过转速偏置信号与上级控制器（如505系列）协同工作。
多模式操作：
提供基本负荷、负荷分配、远程负荷设置及过程控制模式，适用于不同运行场景：
基本负荷模式：直接控制机组输出功率；
负荷分配模式：动态分配多机组并联运行时的负荷；
远程负荷模式：接收4-20mA模拟信号或上位机指令调整负荷；
过程控制模式：根据外部工艺需求（如压力、温度）调节发电机输出。
安全保护机制：
集成软件卸载功能，可在异常情况下强制机组降功率，并触发断路器断开指令，确保电网稳定。
2.技术参数与接口
电力参数监测：
通过PowerSense板采集PT（电压互感器）和CT（电流互感器）信号，计算并输出Hz、Vac、Amps、W、VA、VAR、PF等参数，支持IEEE 1459-2000标准算法，实现谐波分析与负序分量监测。
通信与扩展：
支持Modbus通信协议，可连接外部HMI或上位机系统；
配备RS-232/RS-485接口，兼容主流工业控制网络；
提供4-20mA模拟输出（如同步示波器、发电机测量信号）。
3.技术优势
高精度与可靠性：
采用硬PLC架构（LD指令处理器），响应时间<20ms，符合IEC 61000电磁兼容标准，MTBF超过50,000小时。
模块化协同：
可与伍德沃德其他模块（如EGCP-3系列、505控制器）无缝配合，构建分布式电力控制系统。
WOODWARD 5461-654 is a core digital controller designed by Woodward for power systems and industrial automation,integrating synchronization control,load management and power parameter monitoring.The following are its core functions and technical features:
1.Core functions
Synchronization and load control:
Supports use as an independent synchronizer or synchronizer+load controller,which can achieve frequency,phase matching and voltage regulation when the generator is connected to the grid,and work with the upper controller(such as 505 series)through the speed bias signal.
Multi-mode operation:
Provides basic load,load distribution,remote load setting and process control modes,suitable for different operating scenarios:
Basic load mode:Directly control the output power of the unit;
Load distribution mode:Dynamically distribute the load when multiple units are running in parallel;
Remote load mode:Receive 4-20mA analog signal or upper computer command to adjust the load;
Process control mode:Adjust the generator output according to external process requirements(such as pressure,temperature).
Safety protection mechanism:
Integrated software uninstall function can force the unit to reduce power under abnormal conditions and trigger the circuit breaker disconnection command to ensure grid stability.
2.Technical parameters and interfaces
Power parameter monitoring:
The PowerSense board collects PT(voltage transformer)and CT(current transformer)signals,calculates and outputs parameters such as Hz,Vac,Amps,W,VA,VAR,PF,etc.,supports IEEE 1459-2000 standard algorithm,and realizes harmonic analysis and negative sequence component monitoring.
Communication and expansion:
Support Modbus communication protocol,can be connected to external HMI or host computer system;
Equipped with RS-232/RS-485 interface,compatible with mainstream industrial control networks;
Provides 4-20mA analog output(such as synchronous oscilloscope,generator measurement signal).
3.Technical advantages
High precision and reliability:
Adopts hard PLC architecture(LD instruction processor),response time<20ms,complies with IEC 61000 electromagnetic compatibility standard,and MTBF exceeds 50,000 hours.
Modular collaboration:
Can work seamlessly with other Woodward modules(such as EGCP-3 series,505 controller)to build a distributed power control system.
