Course OV370-WIN

Overview

This course is designed to provide in-depth information about the Ovation® Turbine Control System (TCS). Turbine simulators will be used to demonstrate turbine operation, graphics and control logic. Turbine overspeed protection and trip functions will be closely examined. This course includes calibration and troubleshooting exercises on the Speed Detector and Valve Positioner modules. Students will also learn how to tune the turbine control feedback loops and turbine valve curves using methods developed by Emerson.

Prerequisites

Students must have a good understanding of the Ovation system architecture. It is recommended that students attend the OV100-WIN,and OV210-WIN as well as either the OV200-WIN-3.0.X or OV200-WIN-3.1.X courses prior to attending this course.

Duration

Five Days

Objectives

Upon successful completion of this course, using the reference material provided, the student will be able to:

• Understand key Ovation operator functions as they apply to turbine control including the process graphic, alarm, trend, and point information systems
• Identify basic functions of turbine control logic drawings
• Recognize how the turbine control logic connects to the turbine control graphics
• Identify the fail-safe design components: (1) power, (2) controller, (3) relay module
• Understand the Turbine First Out trip logic and Sequence of Event (SOE) alarm reporting
• Configure and test a Speed Detector module
• Configure and calibrate a Valve Positioner or Servo Driver module
• Identify logic sheets that require field tuning
• Discuss field-proven tuning examples
• Retrieve historical trend data for valve curve tuning \
• Import data into an Excel spreadsheet; calculate and plot new valve curves
