Description
Technical field
The present invention relates to transformer station's technology and automation of transformation substations technology, relate in particular to energy-saving digital substation.
Background technology
For the digital transformer substation Study on Technology, abroad walk early.Be specially the following aspects:
Aspect standard, IEC concentrates international mainstream scientific research institution and manufacturer just to formulate the IEC61850 series standard since nineteen ninety-five, has finished the issue of IEC61850 standard family at present; And begin exposed problems in the test application is revised, carry out the writing work of second edition.
Aspect equipment, reach its maturity based on optical fiber and electronic mutual inductor, the intelligent High-Voltage Electrical Appliances technology of different principle, in many transformer stations of global different regions successful Application.
Aspect tentative Demonstration Application, the product that overseas enterprises such as ABB, SIEMENS, ALSTOM satisfy this standard series has also begun the large-scale promotion application, and has built several experiment transformer stations; All there is demonstration project in states such as the U.S., Germany, Holland, in order to validation criteria, promote the further perfect of standard by the time; In Germany a demonstration project is arranged, that participates in this engineering has companies such as Siemens, ABB, ALSTOM, and its final report is delivered in CIGRE meeting in 2000; 2000, in order to verify the feasibility of IEC61850, an experimental enviroment has been built by United Power Company of company such as Siemens and ABB, has successively carried out 6 interoperability tests, and empirical tests satisfies the real-time responsiveness of electric substation automation system and interconnected requirement fully; In November, 2004, the 16kV electric substation automation system of Siemens on Switzerland has put into operation in the world first complete 61850 meaning.
But in general, external research is limited to the restriction of its power network development, and how from standard and tentative angle, representativeness is not strong; In addition, owing to electric power network technique situation gap, administration of power networks require different, social economy's demand difference, determined Chinese electrical network must carry out the road of innovation with self-character.
With regard to domestic, digital transformer substation has become a big focus of current construction and transformation at present, specifically is reflected in the following aspects:
From standard angle, domestic since 1999 just the someone be concerned about IEC61850, this standard was followed the tracks of, studies from institute in south since 2000.At present, southern auspicious science and technology, DianKeYuan, four directions, Nan Ruiji are protected, are permitted to continue, domestic main flow producer such as Dongfang Electronics is just at active research and exploitation Related product, and domestic degree of concern and research and development for IEC61850 drop into just day by day and strengthen.Rise the end of the year 2004, and the taken the lead interoperability test of 6 relevant IEC61850 of state net state accent center is arranged, user and producer for IEC61850 at home application and the prospect thereof on the digital transformer substation formed basic Consensus.
The slave unit angle, domestic main flow producer developed the required main protection of digital transformer substation, observing and controlling, so record, be equipped with equipment such as throwing, metering, and carried out uniformity test substantially.
From the experiment and demonstration angle, trial run has been built up and dropped into to the pilot application project of some digital transformer substations.Based on the digital mutual inductor and the intelligent High-Voltage Electrical Appliances of different principle, many transformer stations in different regions have begun to try out.
From energy-conservation angle, both at home and abroad concrete electric equipment energy-conservation launched more research, after the energy crises in 1973, each developed country has all dropped into a large amount of research and development energy aspect device energy conservation.At present existing many matured products:, and all obtained extensive exploitation and utilization as geothermal heat pump air-conditioner, intelligent temperature and humidity controller, solar photovoltaic generation system, LED electricity-saving lamp etc.But these products are at the rarely seen report of the use of transformer station.
Summary of the invention
Purpose of the present invention is exactly in order to overcome the defective that above-mentioned prior art exists, a kind of high-efficiency reliable energy-saving digital substation to be provided.
Purpose of the present invention can be achieved through the following technical solutions: energy-saving digital substation, it is characterized in that, this transformer station comprises substation level, wall, process layer, high-tension apparatus, described substation level by behind the wall, process layer with the high-tension apparatus control connection, described wall is located on the process layer.
Described substation level is provided with a plurality of functional modules, and to realize required function, described substation level is connected with distant place control centre.
Described wall is provided with a plurality of protection modules, a plurality of control module, and described protection module and control module connect one to one, and described a plurality of control modules interconnect.
Described protection module is connected with the Remote protection center.
Described process layer is provided with the process layer interface, and this process layer interface comprises transducer, operating mechanism.
The signal of described sensor acquisition high-tension apparatus, the running of described operating mechanism control high-tension apparatus.
Compared with prior art, advantage of the present invention is the modernization level that has improved power grid construction, strengthen the ability of power transmission and distribution and dispatching of power netwoks, reduced the total cost of transformer substation construction, and realized the target of the collection of all information in the transformer station, transmission, processing and control total digitalization.
Description of drawings
Fig. 1 is the schematic diagram of the utility model energy-saving digital substation.
Embodiment
The present invention will be further described below in conjunction with specific embodiment.
The utility model is mainly finished an electric equipment and is realized digital communication, the digitlization primary equipment all carries out data modeling according to the unified standard platform in full station (IEC61850 standard) with the secondary intelligent apparatus and communicates by letter, and realizes interoperability each other on the basis of this platform.
The utilization of digital transformer substation technology helps the safe and stable operation of transformer station, also helps transformer station and reduce cost:
