Description: Woodward’s 505 and 505E digital controls use a 32-Bit Microprocessor to control industrial sized steam turbines, small utility turbogenerators, or turboexpanders. The 505/505E package consists of printed circuit boards in an enclosure designed to be mounted within a system control panel. An optional NEMA 4X enclosure is available to allow these controls to be mounted within harsh environments.
Applications: The 505 and 505E are microprocessor based controls designed to operate steam turbines of all sizes. The 505 is designed to operate steam turbines using one or two (split-stage) actuators to drive inlet steam valves. The 505E is designed to operate single extraction and/or admission steam turbines. These digital controls are field programmable. They use menu-driven software to instruct site engineers on programming the control to a specific generator or mechanical drive application. The 505 or 505E can be configured to operate as a stand-alone unit or in conjunction with a plant’s Distributed Control System.
Functionality505 and 505E’s control capabilities are:
- Speed/Frequency Control
- Turbine or Generator Load Control/Limiting
- Turbine Inlet Header Pressure Control/Limiting
- Turbine Exhaust Header Pressure Control/Limiting
- Plant Import/Export Power Control/Limiting
- Isochronous Load Sharing between units (with DSLC)
- Extraction and/or Admission Header Pressure Control (505E)
- Any process directly related to unit load
