Woodward 505 Digital Controller (new) 8200-1300 for steam turbines

The 8200-1300,woodward 505 is a combination of a field-configurable steam turbine control unit and an operator control panel (OCP). The 505 has a comprehensive graphical operator control panel display and keyboard on the front panel. The display can be used for on-line program adjustment and turbine/system operation on the 505 configuration. Easy-to-understand instructions allow the operator to view actual and set values at any time during turbine operation. To meet ATEX/IECEx certification requirements, the 505 digital controller shall be installed in a case coded Ex nA, providing low IP54 entry protection. The installation personnel shall ensure that the high ambient air temperature at the final installation location does not exceed the rated temperature of +70?. 505 controllers should not be installed in areas that exceed “Level 2 contamination” as defined by IEC 60664-1. During normal operation, people should not be able to access the inside of the housing without using tools.

The 505 controller is designed to control single or double (split) actuator turbines (the 505XT version is required for extraction turbines). The 505 is field programmable, which allows a single design to be used for many different control applications, reducing and shortening delivery times. It uses menu-driven software to guide field engineers in programming the controller for a specific generator or mechanical drive application. The 505 configuration can be configured to operate as a stand-alone unit or in conjunction with the distributed control system of the power plant. The 8200-1300 505 controller has five PID controllers that can affect the demand for inlet flow into the turbine: the speed/load PID controller, the auxiliary PID controller, the auxiliary 2 PID controller, and the cascade PID controller. Depending on the 505 configuration, these Pids interact differently with each other. To fully understand the PID relationship, refer to the block diagrams listed later in this chapter. An additional PID is available as a separate control loop, which is optional and can be used to drive an independent analog output signal for any single-loop auxiliary control that may be required (i.e. not to drive the steam valve), such as sealing gas, gland seals, or oil pressure loops. When using isolated PID control, you are advised to select the Enable Read Back Fault option for the analog output channel that is configured as Isolated PID Requirement. If a fault in the output circuit is detected, this triggers an alarm in 505. By default, the analog output channel is not configured to generate an alarm when the output circuit fails. The 505 drives one or two turbine throttle valves to control one turbine parameter at a time and, if necessary, to restrict turbine operation based on other parameters. This controlled parameter is usually speed (or load), however, 505 can be used to control or limit: Turbine inlet pressure or flow, exhaust pressure (back pressure) or flow, stage pressure, generator power output, plant input and/or output level, compressor inlet or discharge pressure or flow, unit/plant frequency, process temperature, or any other process parameter associated with the turbine.
