pl give me a detailed write up & coloured drawings for the governing system of 210/200 m.w kwu turbines. Also a copy of the same for 500 m.w Units.

I am not getting any help from this site in getting the thing I wanted.

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] Throttle governing.

Steam turbine governing is the procedure of controlling the flow rate of steam to a steam turbine so as to maintain its speed of rotation as constant. The variation in load during the operation of a steam turbine can have a significant impact on its performance. In a practical situation the load frequently varies from the designed or economic load and thus there always exists a considerable deviation from the desired performance of the turbine.[1] The primary objective in the steam turbine operation is to maintain a constant speed of rotation irrespective of the varying load. This can be achieved by means of governing in a steam turbine.
