Description
Technical field
The utility model relates to box-type substation technical field, particularly relates to a kind of photovoltaic case change protection telemetry communication integrated apparatus supporting IEC61850.
Background technology
Case change is the abbreviation of box-type substation, and box-type substation is again prepackage type electric substation or preassembled transformer station.That a kind of high voltage switchgear, distribution transformer and low-voltage distribution equipment are by indoor, the outdoor close-coupled controller switching equipment of certain connection plan row's all-in-one-piece prefabrication, organically combine by functions such as high powered, transformer pressure-reducing, low-voltage distributions, be arranged in a protection against the tide, antirust, dust-proof, protection against rodents, fire prevention, antitheft, heat insulation, totally-enclosed, moveable steel construction casing, electromechanical integration, totally-enclosed operation, be specially adapted to urban network construction and upgradation, a kind of brand-new transformer station emerged after Shi Ji civil engineering transformer station.Box-type substation is applicable to mine, factory and enterprise, oil gas field and wind power station, and it instead of original civil engineering power distribution room, power distribution station, becomes novel complete power distribution equipment.Box-type substation is applicable to residential quarters, urban public, bustling downtown area, construction power supply etc., and user can select box-type substation according to different service conditions, load level.Box-type substation is since appearance, and development is very rapid, and accounted for 70% of distribution transformer at countries in Europe, the U.S. accounts for 90%.Along with the develop rapidly that Modernization is built, the continuous renewal transformation of urban power distribution network, box-type substation will be widely used.
China is from 20 century 70 later stages, introduce and imitated box-type substation from French, German etc., adopt high-low voltage switch cabinet from structure, transformer building form, this box-type substation is called that European-type box becomes, and Vivid analogy is to high-low voltage switch cabinet, transformer cover house.Wherein, the casing that European-type box becomes is made up of base, shell, top cover three part.Base generally uses channel-section steel, angle steel, band steel, steel plate etc., assembly welding or be joined with bolts shaping; For the needs of satisfied ventilation, heat radiation and line, also output the circular port of bar hole and size appropriateness in relevant position.Cabinet shell, top cover channel-section steel, angle steel, steel plate, aluminium alloy plate, color steel, cement plate etc. carry out bending, assembly welding or with screw, hinge or relevant special accessories joint forming.It is provided with independently transformer room, transformer room primarily of transformer, automatic temperature control system, illumination and the formation such as safety guide rail.
From the nineties in 20th century, China introduces U.S.'s box-type substation, and structurally by on-load switch, loop networks switch and fuse structure simplification are put into oil tank of transformer and be immersed in oil.Lightning arrester also adopts oil immersed type zinc oxide arrester.Conservator cancelled by transformer, and fuel tank and radiator expose in atmosphere, and this box-type substation is called American Unit Substation, and Vivid analogy is that transformer side hangs a chest.American Unit Substation becomes from European-type box at first and develops, and its volume is often huger, and its overload capacity is strong, allows overload 2 times 2 hours, transship 1.6 times 7 hours and do not affect the case change life-span.It adopts elbow formula connection-peg, can the connection of very convenient high pressure inlet wire cable, and can in case of emergency use as on-load switch, can charged plug.It adopts double fuse to protect, and plug-in fuse is the open circuit fault that Lazer's fuse (temperature, electric current) guard box becomes secondary side generation.Standby current-limiting protection fuse guard box becomes the inner fault occurred, for the protection of high-pressure side.It generally adopts high fuel oil point.Its high voltage load switch protection fuses etc. all element are all placed in same fuel tank with transformer core, winding.
At present, home box transformer substation is compared with American Unit Substation, adds earthed switch, lightning arrester, has mechanical interlocking between earthed switch and main switch, can ensure like this carry out case become safeguard time being perfectly safe of the person.Its every two fuses protections that instead of American Unit Substation mutually with a fuse, its maximum feature is after arbitrary phase fuse blows, all can guaranteed load switch trip and cutting off the electricity supply, and after only having replacing fuse, main switch just can close a floodgate.
Wherein, IEC61850 standard is the unique international standard of electric substation automation system based on universal network communication platform, it is responsible to define by 3 working groups 10,11,12 (WG10/11/12) of technical committee of International Electrotechnical Commission the 57th (IECTC57).As the international standard that the transformer station of communications platform Network Based is unique; the IEC61850 standard absorption experience of IEC60870 series standard and UCA; the simultaneously stability technology of a lot of advanced person, produces deep effect to the design of the automated productions such as protection and control and electric substation automation system (SAS).It will not only be applied in transformer station, and will apply between transformer station and control centre and between control centre at different levels.Its main feature comprises: the hierarchical information 1) defining transformer station; 2) have employed OO data modeling technology; 3) data self-described; 4) network independence.Domestic and international Ge great Utilities Electric Co., research institution are all actively adjusting research and development of products direction, try hard to integrate with new international standard, to adapt to following developing direction.
But, in recent years, although China's new forms of energy industry development is comparatively rapid, especially in field of photovoltaic power generation, due to the support energetically of national policy, enter the blowout formula high speed development stage at present.In the process of development, relevant auxiliary facility, the case especially centered by box type transformer becomes protection supervisory equipment, and most product function is not comprehensively, Information Monitoring amount is limited, product function degree of integration is not high, communication interface is limited.Major part case becomes measure and control device and limits due to plant bulk, electric parameters amount of acquisition channels is limited, open less into amount of acquisition channels, that communication interface only supports negligible amounts RS485 serial ports, Ethernet and optical fiber ring network communication, communication protocol only supports Modbus or IEC103, does not support electric substation automation system international standard IEC61850 of new generation, does not support the functions such as wireless senser access and video frequency pick-up head access.
Existing a lot of automated system supports IEC61850 standard at present, and case becomes measure and control device as the core of photovoltaic generation, does not also have the complete box-type substation according to this standard design at present.
