WOODWARD 505D 8200-1301 is a digital speed governor produced by Woodward, mainly used for the control of steam turbines. The following is an introduction to its specifications, parameters, and application scenarios:
-
Specifications and Parameters
- Power Input: AC 88-264V, 1.6-0.9A, 47-63Hz; DC 90-150V, 0.8A.
- Operating Temperature Range: -30°C to 70°C.
- Weight: Approximately 6.28kg.
- Communication Interfaces: Supports Ethernet communication, which can connect to factory DCS, service tools, and remote operation control panels; equipped with a Canopen interface for connecting Woodward variable stroke actuators and DSLC – II power management networks.
- Other Features: Integrates a graphical front-panel HMI screen that supports multiple languages including Chinese; has an internal “turbine simulator” for offline training and advanced testing before system changes; features high-speed data recording function to monitor turbine operation and stress, etc.
-
Application Scenarios
- Steam Turbine Control: Mainly used to control steam turbines, enabling precise adjustment of steam turbine speed to ensure stable operation.
- Split-range or Single-actuator Control: Suitable for split-range or single-actuator control scenarios, and can flexibly adjust the control mode according to actual needs.
- Integration with DCS System: Can be configured as part of a factory DCS (Distributed Control System) or used as an independent unit to realize comprehensive control and management of the steam turbine.
Its working principle is to receive the speed signal from the magnetic sensor or proximity probe on the on-site steam turbine body, compare it with the set value to generate a deviation, and after amplification, control the governor’s electro-hydraulic control mechanism to adjust the speed. At the same time, it can form a cascade regulation system with the steam turbine load regulator to realize the regulation of the steam turbine load.
