Internet and thermal power plant heat production operation integrated management platform

Abstract

The invention discloses an internet and thermal power plant heat production operation integrated management platform. The internet and thermal power plant heat production operation integrated management platform comprises a centralized dispatching control center, six important functional subsystems such as a heat and power generation optimized dispatching subsystem, a heat transmission and control subsystem, a pipe network safety management subsystem and the like, as well as long-distance pipe networks and user control terminals, wherein the user control terminals are accessed to the internet through a mobile communication network; the centralized dispatching control center and the functional subsystems are connected with each other through an industrial control network and connected with the internet; the heat and power generation optimized dispatching subsystem is connected with DCS of each generator set through the industrial control network; and the heat transmission and control subsystem is connected with each long-distance pipe network and each user control terminal through the internet and the mobile communication network. Through the internet and the private network, the heat production and operation businesses and the target requirements of the thermal power plants are integrated on one platform, so that the data share and business integration are realized, the production and operation efficiency is optimized, and the economic dispatching operation level and the enterprise management level are improved.

Description

technical field [0001] The invention relates to a brand-new application of Internet + thermal power plant thermal production operation management, which belongs to the application field of Internet + industrial control and remote communication technology. Background technique [0002] With the advancement of the national "energy saving and emission reduction" policy and air pollution prevention and control actions, small thermal power plants with high pollution and high energy consumption have been gradually shut down, replaced by more and more large coal-fired units that have begun to supply heat externally. The main power plants have gradually become thermal power plants through heat supply transformation, and heat production and operation management have become one of the main businesses of these power plants. [0003] At present, with the development of thermal insulation technology for heating pipes, the heating distance of thermal power plants is getting longer and wid...

AI Technical Summary

Problems solved by technology

[0003] At present, with the development of thermal insulation technology for heating pipes, the heating distance of thermal power plants is getting longer and wider, the heating range is getting larger and larger, and the heat users are becoming more and more scattered. However, thermal power plants still stay in the traditional mode of heat production and operation management. The technical level is not high, the management is relatively extensive, and the aspects of planning, economy, real-time, openness, and labor efficiency need to be improved urgently

The main disadvantages are as follows: 1) A single heat supply adjustment method, that is, only adjusts the heat supply at the total outlet of the power plant, causing the entire pipe network’s thermal parameters (flow, pressure, temperature) to increase and decrease together, for each The thermal parameters of the branch pipe network and users lack remote and precise adjustment and control means, which may easily cause losses and uneconomical in the process of heat transmission

2) The lack of predictability and planning of heat production will cause fluctuations in power generation production. Since the needs of heat users cannot be obtained in advance, heat production can only change with the actual needs of heat users, resulting in the mutual influence of thermal power and power generation in thermal power plants. Poor response speed and accuracy to grid and user needs

3) The level of emergency management is low, and there is a lack of technical means for emergency response. That is, when a thermal power plant unit or a branch line of a pipe network fails, it can only be notified by telephone, and the load cannot be removed or transferred immediately, which may easily cause a large heat supply interruption.

4) Most of the metering and settlement of hot users adopt manual methods, that is, manual meter reading, manual bill making, express delivery of bills, door-to-door charges, bank transfers, etc. Although there are also pre-paid and online banking methods, they are still relatively backward
