Description

City heat supply energy consumption wisdom management and control technology platform
Technical field
The present invention be directed to concentrated supply of heating in the city energy consumption pipe network, a kind of real-time dynamic energy consumption monitoring operation system of research and development. It is mainly used in providing the technology branch of heat supply decision scheme and each heat supply related link of long-distance intelligent control for heating enterprise, heating plant Hold;There is provided for terminal user and use hot decision scheme, to realize the target of low-carbon heat supply and effective heat.
Background technology
Energy industry is a new industry, is related to energy-conserving and environment-protective, in the case where using energy source is more and more nervous, the world The numerous and confused industry that will save in various countries is placed on prominent important position, investment significant capital research energy-conserving and environment-protective measure, therefore brings The fast development of the industry, energy saver is even more with rapid changepl. never-ending changes and improvements with technology.What China promulgated for 1997《The People's Republic of China (PRC) saves About energy law》In just clearly propose to need propulsion energy-saving technological progress, the reduction energy consumption per unit of output value and energy consumption of unit product improve energy Exploitation, processing conversion, conveying and the supply in source, step up efficiency of energy utilization, promote national economy to energy-saving development. Executive Meeting of the State Council in 2007, determining will《Civil Building Energy Conservation regulations (draft)》Consulted on to society's announcement.《Draft》 In clearly, country actively pushes forward supply hot water reform, improves heat supply pricing mechanism, encourages development central heating, progressively real Row is according to using heat fee system.For new building energy-conservation,《Draft》Regulation, carrying out the building of central heating should install point Family indoor temperature regulation device, and installation point or point family heat metering device and heating system regulation device;Built for existing Build energy-conservation,《Draft》Especially clearly, " reducing energy consumption is carried out to the residential architecture for carrying out central heating, should install point or divide Family heat metering device and heating system regulation device ".It can thus be seen that country is to the firm of construction of energy conservation-minded society It is determined, and to the purpose of cities and towns heating system reform.
" the Developing Energy-saving Construction annual report in 2007 " held according to Tsing-Hua University understands that heating energy consumption accounts for Chinese north The overwhelming majority of mahjong town building energy consumption, accounts for the 40% of whole nation building total energy consumption.With the continuous quickening of Process of Urbanization Construction, cities and towns Heat supply network will continue to expand, and according to current development speed, if not taking conservation measures, 3 are up to the year two thousand twenty heating energy consumption Hundred million tons of standard coal/years.In the reason for causing China's central heating system inefficiency, following reason can not be ignored:
(1)Thermal source efficiency is low:The recycling of thermal source waste heat is improved, is realized according to the change of the thermic load of whole system to heat Source power carries out dynamic regulation, can improve thermal source efficiency.
(2)Lack permanent room temperature regulation mechanism:There is windowing radiating without room temp regulator in current most of users Situation.
(3)Lack efficient heat measuring method:The investment of heat distribution list method is big;Calorimeter method is difficult in maintenance, installation effectiveness It is low, make the two all be difficult to promote the use of;Conventional area method lacks fairness again, and user does not receive;Time break-make method and discharge method It is higher to water quality requirement using being restricted.
(4)System control strategy is not perfect enough:The quantity of heat given up of source center and thermal substation should be with the change of load And change, central heating system subsystems at different levels should carry out through transport control, could only in this way realize whole central heating system The energy-conservation of system.
Heating central heating system is widely used in the northern area of China, and the defeated heating system of heating power be a high energy consumption, The industry of high pollution, therefore the utilization rate of energy is improved, reduce energy dissipation and be just particularly important.However, in existing skill In art, the utilization of heating is relatively simple, and indoor temperature is controlled only according to the artificial control valve air inflow of empirical value.This control Mode processed can not be accurately controlled indoor temperature, influenceed heating quality, caused the utilization ratio of heat more low, pole Big wastes the energy;Due to heating of being pressurizeed in whole cell set, different units, user's heater temperature phase of different floors are caused Difference is very big, often causes user's discontented.
A kind of " CN201520378206.8 " novel intelligent heat supply managing system is taken using technologies such as RS-485 and GPRS Build heat supply managing system, realize long-distance metering and break-make user's heat supply, but be not directed to the regulation and control of user terminal problem, heat exchange station monitoring, Upper system monitor supervision platform builds the research and design with pipe network control strategy optimization;
" CN03133353.2 " heating management management information system, proposes the neural Meta algorithms of BP being applied to heating network Automatically control, and propose user terminal temperature is accurately controlled, but its invent scope of design be to be related in management The heart does not refer to that the design, control and communications platform of user terminal are built to heat exchange station, and the invention also emphasizes that it belongs to all the time Computer control field, its design focal point is building for administrative center's control platform.
" CN200810154469.5 " large area heat supply running automatic monitoring system device, simply proposes a kind of city-level In the range of heating supervision platform building imagination, its bottom monitored object it is final towards be each section, can not be to heat Terminal is effectively monitored, and does not also propose effectively to save practice weekly notes.
" CN201120112054.9 " neighbours living temperature acquisition and monitoring system and " CN201420473434.9 " one Plant heat supplying managing system, it is proposed that a kind of control strategy of cell boiler heating, controlled by the supply and return water temperature to boiler System, it is ensured that user terminal temperature;But itself and not face central heating, and it is related to faciostenosis, control strategy is simple.
" CN201210185265.4 ", a kind of heat death theory Information Remote Transmission System based on composite communication mode, simply It is simple that user terminal is acquired with dsc data, transmits and is not directed to any control and conservation measures.
