WOODWARD 5461-647 is a high-performance digital controller designed by Woodward for generator sets and industrial process control.It is designed to provide high-precision control and protection functions for complex power systems.The following are its core functions and technical features:
1.Core functions
Load distribution and process control:
By accurately calculating the electrical parameters of the generator and bus(such as voltage,current,power,etc.),dynamic load distribution and process control are realized,and key operations such as unit grid connection and decoupling are supported.
Software unloading and circuit breaker control:
When receiving abnormal instructions,the software unloading function can be triggered to force the unit to reduce power and issue a circuit breaker disconnection instruction at a preset level to ensure system safety.
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 ensures data accuracy.
2.Technical parameters and interfaces
Analog output:
Supports 4-20mA analog output,optional synchronous oscilloscope,generator measurement or mains measurement function,easy to integrate into the monitoring system.
Digital input/output:
Compatible with digital signal input,used to receive sensor or PLC instructions,supports hard PLC(LD instruction processor)architecture,and achieves fast logic response.
Communication capability:
Supports RS-232/RS-485 interface,can communicate with the host computer or DCS system,and expand the control range.
3.Technical advantages
High-precision calculation:
Based on the algorithm of IEEE 1459-2000 standard,it can analyze the harmonic components and negative sequence components of voltage and current in real time to improve the stability of the power system.
Modular design:
It can work with other Woodward modules(such as EGCP-3 series)to form a distributed control system to meet the needs of generator sets of different sizes.
Reliability:
Industrial-grade protection design,supports wide temperature working environment,and anti-electromagnetic interference capability meets industry standards to ensure long-term stable operation.
