Emerson 5X00497G01 Overview 4 slot I/O basic unit module

Description

Steam 5X00497G01 turbines are used in many electrical power generation plants. The electrical

load on a steam turbine’s electric generator flfluctuates as the electric power

consumption increases or decreases. The Digital Electro-Hydraulic (DEH) control

system provides turbine control to adjust steam 5X00497G01 turbine shaft rotational speed in

response to varying electric generator loads. Very large amounts of force are

required to move valves on large turbines. Therefore, an interposing device is

required between the DEH control system and the controlled valves.

The 5X00497G01 Ovation Servo Driver module provides an interface between an Ovation

Controller and an electro-hydraulic servo valve actuator. Each controlled turbine

valve is connected to an electro-hydraulic actuator (servo-motor). A servo-motor is

a flfluid operated piston. Admission of high pressure hydraulic flfluid to the piston

cylinder is regulated by a smaller pilot valve. The pilot valve passes hydraulic flfluid

underneath the piston to raise it and the controlled valve, or it diverts hydraulic flfluid

to the upper side of the piston to lower it and the controlled valve.

A valve position set point is maintained by the 5X00497G01 Ovation Servo Driver Electronics

module. The set point is normally altered by the Ovation Controller via the I/O bus.

Inside the Electronics module, a microcontroller provides closed loop proportional

plus-integral (PI) control for real time valve position control.

The valve position set point causes the Servo Driver module to generate an output

control signal that drives the electro-hydraulic servo valve actuator coil. The

feedback loop is closed with the 5X00497G01 valve’s position measurement being obtained from

a DC-LVDT or an AC-LVT that is mounted on the valve stem.

The electronics module will interface two Electro-Hydraulic (EH) actuators in the

fifield. The module provides two independent channels that are electrically isolated

from each other.

The Servo Driver Module is NOT applicable for CE Mark Certifified Systems.
