AI Technical Summary

Problems solved by technology

When using the mode of sealing the fuel injection volume of the external characteristics of the engine, in the speed regulation section, due to the influence of high and low idle speed intervention and drastic changes in fuel volume, when the speed changes slightly, it will cause drastic changes in the fuel injection volume, resulting in The speed fluctuates greatly and the control is unstable
Although the generator sets using this mode can be connected to the grid, the consistency is difficult to guarantee, and there are also problems in the splitting, paralleling and load distribution of multiple machines

Embodiment Construction

[0045] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] The invention provides a control method of an engine for power generation, which is especially suitable for electronically controlled diesel engines in power generation equipment.

[0047] refer to figure 1 , which shows a schematic diagram of an embodiment of the control method of the engine for power generation according to the present invention, including:

[0048] Step 1. Obtain the basic set value V of the engine speed 0 ;

[0049] Step 2. Use the load feedback and the fine-tuning of the grid-connected speed to correct the basic set value V of the engine speed 0 , to obtain the final set value V of the engine speed; wherein, the fine-tuning amount of the above-mentioned grid-connected speed can be obtained by adjust...

Abstract

The invention provides a power generating motor control method and device and a power generation device. The power generating motor control method includes: obtaining basic set values of motor rotating speed; rectifying the basic set values of the motor rotating speed through load feedback and synchronized rotating speed fine adjusting amount; calculating rotating speed difference of the final set value of the motor rotating speed and actual motor rotating speed; converting the rotating speed difference into torque; converting the torque into final fuel injection quantity. By means of the power generating motor control method, synchronization, disconnection and load proportion distribution of a plurality of power generation devices can be achieved easily.

Description

technical field [0001] The present invention relates to the field of engine technology, in particular, to a control method and device for an engine for power generation, and power generation equipment. Background technique [0002] With the increasingly stringent emission regulations and the enhancement of people's awareness of environmental protection, the electronic governors used in power generation equipment with mechanical pump engines at this stage can no longer meet the needs of the market. In this context, power generation equipment using electronically controlled engines came into being. The power generation equipment has the following advantages: 1) The engine runs smoothly, and the steady-state regulation rate of the unit is small; 2) When the unit suddenly loads, the response is sensitive, and the transient regulation rate and stabilization time are better than those of the electronically adjustable mechanical pump; 3. ) has good fuel economy, and its emissions ...
