A steam generator controller

Abstract

The invention discloses a steam generator controller. The steam generator controller is used to regulate and control a steam power machine, an acceleration mechanism and an electric generator. The steam generator controller comprises a microprocessor and a power module, and further comprises an encoder, a flow regulating valve, a monitor, a temperature sensor, a humidity sensor, an oil pump, a motor, a control panel, an air fan, a heat dissipation pipe and an oil tank. The steam generator controller uses an embedded control system as a core, can monitor work status of the electric generator, intelligently regulates and controls the work status of the electric generator, and is convenient to operate, simple and easy to control, and easy to popularize and use.

Description

technical field [0001] The invention relates to the technical field of steam power generation control, in particular to a steam generator controller. Background technique [0002] In the process of steam power generation, parameters such as steam flow and temperature are often unstable and vary greatly. In addition, operations such as starting and stopping of load equipment will cause power changes at the output end of the generator, which increases the difficulty of output power quality control. The change of any of the above-mentioned factors will cause the output power of the generator to be unstable. In practice, two or more factors usually change and interact at the same time, which then makes the output power of the generator more unstable. In view of this situation, the existing solution is to form a closed-loop regulation loop by detecting the generator speed and controlling the opening of the steam flow regulating valve, so as to achieve the purpose of stabilizing t...

AI Technical Summary

Problems solved by technology

However, the internal energy contained in steam is not only related to the flow rate, but also related to parameters such as temperature and pressure. Therefore, the single variable adjustment method cannot better convert the internal energy of steam into electrical energy, resulting in low thermal energy conversion efficiency.

[0005] (2) Inconvenient operation

The main performance is that after the commissioning of this kind of controller is completed, various control parameters in the program are relatively solidified. Once the fluctuation of the steam characteristics exceeds the original preset range, it is very difficult for the operator to modify or debug again, and usually only professionals can On-site debugging; some controllers will design operation buttons, but because of the lack of relevant interactive means, non-professionals cannot accurately predict the control effect of the parameter modification when modifying the control parameters, and the ideal control purpose cannot be achieved , or even cause the equipment not to work properly or cause an accident

[0006] (3) Inconvenient management

The main manifestations are: this kind of controller is mainly aimed at a single generator set, and it works in isolation, so it is not easy to realize unattended in the true sense. Once a fault occurs, even if the controller itself has a self-protection function, due to Its working status cannot be understood by other equipment or the monitoring room, so it will cause inestimable damage to its related equipment, which is especially reflected in the load equipment that cannot be powered off, and the use of this unit to reduce the pressure of pipeline steam involves using steam For the relevant production process or equipment of the working medium

[0007] (4) Inconvenient maintenance

The main performance is that because this kind of controller is designed for a fixed control object, there may be a surplus of control input and output points in some functions, but its reserved function points are also targeted, so it is not convenient for subsequent Some instruments and meters or actuators and other equipment that are newly added or changed to enhance the output power quality cannot meet the needs of subsequent function improvement and optimization; When there is a circuit failure, it is not conducive to quick maintenance and affects the production of the factory

[0008] (5) It is not conducive to the future intelligent upgrade of the factory

Since this kind of controller cannot send status information parameters to the central control system, nor can it accept the control instructions sent by the central control system, this kind of functional "government order" will become an obstacle to the intelligent upgrading of factories in the future, resulting in economic loss on
