Governing System

Governor is a heart component of the turbine which controls it during steady state and transient conditions. The governor does this function by controlling the steam flow through the turbine by adjusting the control value. The governor is a control component with advanced protections for the turbine which ensure safe operation of the turbine. Governing system of the turbine does the following functions:



Controls the turbine speed during start-up or in no load condition to permit the u ....etc

Analysis on the characteristic of the governing system and the primary frequency regulation of Combined cycle units
Abstract:
With the rapid growth of the power grid, it s more and
more important to keep the grid stable using not only secondly
frequency regulation but also primary frequency regulation (PFR)
function. On the other hand, combined cycles units are rapidly
growing in recent years and it s necessary to analysis the PFR
characteristic of them. In this article, the structure and brief
characteristic of the governing ....etc

Excitation and Governing Control of a Powern Generation Based Intelligent System

Abstract
Modern power systems are complex and non-linear and their operating conditions
can vary over a wide range. In this work, the power system (PS) transient terminal
voltage and frequency stability enhancement have been well investigated and studied
through the following efforts.
Enhancing the responses of the transient stability by adopting conventional PID
controllers as an additional voltage controller with the Automatic Voltage Reg ....etc

governing system of kwu turbine

Introduction

To govern means to control and regulate certain parameters to achieve expected functional requirements. Governing system can, therefore be preliminary defined as the system designed to achieve functional requirement of turbo-generator operation by controlling and regulating steam turbine input parameters viz. turbine inlet pressure of steam, mass flow rate of steam etc.

Methods of governing

Generally for utility steam turbines following two methods are popularly used:-1] Nozzle governing-2] Thro ....etc
