Abstract

The invention discloses a configurable integrated digital electro-hydraulic regulator, which comprises all hardware integrated in the same case, wherein a digital quantity input interface, a frequency input detection interface, a 4-20mA input detection interface and a position sensor input interface are connected with a microprocessor through an analog / digital converter; a 4-20mA output interface, a servo output interface and a relay output interface are connected with the microprocessor through a digital / analog converter; and a communication interface, a storage and a touch screen are connected to the microprocessor. By configuring the hardware and a control strategy through software and integrating the touch screen and other hardware in the case, the structure is compact; and the control strategy can be freely configured according to the field and steam turbine characteristics, so that the digital electro-hydraulic regulator in a single type can be suitable for different applicationoccasions, and is favorable for mass industrial production.

Description

technical field [0001] The invention relates to a device for controlling the speed and power of a steam turbine by controlling the opening of an electro-hydraulic servo valve. Specifically, it is a configurable integrated digital electro-hydraulic regulator. [0002] In particular, it is a digital electro-hydraulic regulator that integrates all hardware in one chassis and has a touch screen. The hardware and control strategy can be flexibly configured through software. Background technique [0003] Steam-driven steam turbines are by far the most common means of generating electricity or providing direct rotational power. The steam turbine is usually controlled by the method of controlling the valve by the electronic hydraulic system. With the development of science and technology and the improvement of the application level of steam turbines, the control strategies and monitoring site signals of steam turbines in different sites are often very different, and the personaliz...
