摘要

The demand for Electric power by the year 2005 is estimated to 22% raise (665GW) from the existing power generation capacity in the world as per the report from Utility Data Institute, USA. In the recent past, Gas Turbine based power plants attribute to a significant share of electricity demand besides Thermal, Hydro and Nuclear power plants. This expected power generation capacity to be met by 39% Gas based plant, 34% Thermal plant, 22% Hydro plant, and 5% Nuclear plant as per General Electric company. Gas Turbine based power plants have augmented its significant share of 39% due to its higher efficiency, lower emissions bestowed with greater operational flexibility and availability. The operational flexibility is attained in several means and the most beneficial methods adopted to meet different requirements of the plant are described with regard to Controls and Automation. The probability of plant availability for use and its true virtues in terms of reduction in downtime, and insensitiveness to consequences of failure are focussed. Power Plant configuration, Fuel flexibility, Controls and Automation, configuration, Design objective, Design architecture - Conventional and Fault Tolerant design / Redundancy, Operational flexibility - unit control / Multi-unit control / Control locations and Control Hierarchy / Operator Interface / Fault diagnosis / Design-out maintenance, and integration of different level of control layers and their divergence towards achievement of increased Gas Turbine availability are described.
