Digital Electro Hydraulic Control System

The steam turbine digital electro hydraulic control system is the most important functional subsystem of the turbine power generator.

Digital electro hydraulic control system.

It utilized pure electric and high pressure fuel oil or low pressure turbine oil hydraulic servo system component forming the digital electro hydraulic control system deh. A digital servo drive supplied by paragon energy solutions. The ehc system has both electronic and hydraulic parts. Turbine speed is monitored by a magnetic.

With a well executed hydraulic control system that can work at the speed of digital machines can perform tasks either with minimal interference from the driver or in some cases with no operator at all. An electro mechanical direct coupled actuator. The operator controls and indications for the ehc system can be seen in figure 3 2 3. The advantages are robustness high efficiency energy efficiency as well as a dynamic and highly accurate regulation.

These inputs can be defined as the user interface and can consist of joysticks potentiometers operator panels or other input devices. An electro hydraulic control system use electronic circuits is m. The updated system offers a nuclear qualified woodward 505 digital controller supplied by esi. Electronic control in mobile equipment can consist of the following.

The mitsubishi turbine ehg control system can be applied to a variety of turbine generator system designs. Digital electro hydraulic control system simply called deh system is mainly used as the steam turbine control system to adjust the speed load and exhaust pressure etc. These inputs can be defined as the machine interface and can consist of pressure transducers temperature sensors flow sensors velocity sensors or rpm sensors. Re flexibility but the over all requirements are.

The control system is highly reliable and easy to operate easy to maintenance flexible with features and design focusing on the redundancy of key components self diagnostic on every. Eliminates the issues of hydraulic control and component obsolescence. The turbine electro hydraulic governor ehg control system controls steam flow to the turbine thorough a series of servo driven electro hydraulic valves. A digital electro hydraulic control system.

The rexroth sydfe is an electro hydraulic control system based on an axial piston variable displacement pump for controlling pressure flow and power without throttling losses in the energy line. It can receive on site signals like speed power and steam pressure as well as the instructions from the lcd screen sent by operators.
