Title: Turbine governor change allows wide fuel gas choice

Abstract

The Rolls-Royce Olympus SK30 turbine gen-sets providing power for Marathon Oil`s Brae A platform in the North Sea have recently been refitted with TC95-03 microprocessor governor control systems supplied by Turbine Controls Ltd., of, Leicester, England. The new control systems have been fitted to avoid the poor transient performance and damage that could occur under such conditions. The new fuel control system is designed to detect Wobbe Index variations while maintaining necessary protection and safety requirements of the gas turbine. In addition to being able to cope with varying gas composition, the governor has been programmed to permit variable fuel gas pressure. This has allowed the fuel gas pressure regulator to be removed, thereby eliminating many of the problems associated with the regulator. A fuel gas pressure transmitter has been added. In addition, replacing the governor has allowed some fairly minor modifications to start-up, loading and fuel changeover logic. These have resulted in significant improvements in the start-up and operational reliability.
