Abstract
The invention relates to an arrangement method for underground substations, and the method includes the following steps: 1) confirming a main wire, a high voltage side wire as well as a medium voltage side wire and a low voltage side wire; 2) confirming main equipment, including selecting a transformer, a low voltage reactor and GIS equipment; 3) confirming the model of a cable matched with the equipment as per the model of the selected equipment; 4) selecting the structure form of a substation as per the model and specification of the equipment; 5) confirming the arrangement of a fire extinguishing system and an air prevention and exhaust system as per the structure form of the substation; 6) coordinating surrounding environments as per the design of the underground substation. Compared with the prior art, the arrangement method enables the arrangement of the substation to be reasonable, reduces the occupied land area on the premise of ensuring the performance, optimizes the working environment, ensures the safe operation of the equipment, coordinates with the surrounding environments, and plays a good demonstration function for design and arrangement of further underground substations.
Description
Technical field
The present invention relates to a kind of layout method of underground substation.
Background technology
At present,, implement relatively difficulty of transformer station site, can combine the stage variable pressure construction in suitable site sometimes, combine to build such as 500kV and 220kV, 220kV and 110kV transformer station because the down town land used is nervous.Such construction mode can improve the support situation that the superelevation power grid construction can't really obtain engineering location units concerned.The optimization of emphasis consideration electric network composition when building superhigh pressure transformer station in the past; But can not take into account the on-site terminal of solution workload demand because the outlet electric pressure is too high; After adopting multistage step-down mode, can increase the outlet of the low-voltage that can solve the needs of electricity consumption on the spot; When building the superhigh pressure engineering, need take local need for electricity into account like this, be a technical problem to be solved for the layout of the so large-scale underground substation of 500kV Expo transformer station.
Summary of the invention
The object of the invention is exactly the layout method that a kind of underground substation is provided for the defective that overcomes above-mentioned prior art existence.
The object of the invention can be realized through following technical scheme: the layout method of underground substation may further comprise the steps: 1) confirm main electrical scheme, graceful side joint line and in, the low-pressure side wiring; 2) confirm main equipment, comprise transformer, low tension reactor and the GIS equipment selected; 3) according to the definite cable model that is complementary with equipment of selected unit type; 4) select the substation structure form according to the unit type specification; 5) confirm the layout of fire-fighting system and anti-exhaust system according to the substation structure form; 6) coordinate surrounding enviroment according to the design of underground substation.
Compared with prior art, the present invention makes the rationally distributed of transformer station, under the prerequisite of assurance function; Reduce floor space, optimized operational environment, guaranteed the operation of device security; And with the environment coordination of periphery, the layout of underground substation is from now on had good exemplary role.
Embodiment
The layout method of underground substation may further comprise the steps: 1) confirm main electrical scheme, graceful side joint line and in, the low-pressure side wiring; 2) confirm main equipment, comprise transformer, low tension reactor and the GIS equipment selected; 3) according to the definite cable model that is complementary with equipment of selected unit type; 4) select the substation structure form according to the unit type specification; 5) confirm the layout of fire-fighting system and anti-exhaust system according to the substation structure form; 6) coordinate surrounding enviroment according to the design of underground substation.
The construction scale of transformer station should be taken all factors into consideration definite according to status, regional power supply condition, workload demand, operational mode and the total investment of engineering etc. of the system wiring mode in the residing electric network composition, transformer station's rack of living in.Under the characteristics condition; The planning of underground substation part maybe be different with the consideration of conventional ground transformer station; Should make full use of the site resource for the consideration of underground substation accomplishes planning and layouts; Electrical main connecting wire: the underground substation should be reduced electric pressure and simplify wiring under the condition that satisfies Electric Power Network Planning and reliability requirement.To reach minimum electric component, improve the reliability of equipment.Main equipment selects to combine the characteristics of underground substation; The reliability of equipment, freedom from repairs or few maintenance requirement are high; Consider by following principle: device miniaturization, device efficiency height; Caloric value is few, the temperature rise requirement for restriction high, the type of cooling of oil immersion equipment is chosen in the acceptable scope of cost performance after should carrying out fully relatively, adopts no liquefying apparatus as far as possible, to reduce disaster hidden-trouble and fire-fighting investment.The underground substation at first answers emphasis to confirm that transformer station intends the employing planform aspect layout, and then carries out planar design.Needs in the time of on the layout of integral body, should taking into full account characteristics and installation, equipment carrying, operation maintenance and the enlarging of transformer station.Should consider simultaneously the imagination of structural fire protection during layout synchronously, especially the setting of fire prevention zone, fire escape and vertical channel should be rationally convenient.Take into full account for the rational fire compartment Ying Yu of ultra-large type transformer station.Cable floor rationally is set is convenient to the butt joint of cable tunnel.Heating and ventilation and air handling system also are the requisite systems of a underground substation, and a perfect system can be built a good running environment for the underground substation.Division of equipment room ventilation systems and system form should take into full account the various kinds of equipment operation characteristic and design.Fire-fighting system is relied mainly on prevention in principle, and it is auxilliary disappearing.Should take into full account estimating and the setting of fire alarm system of fire risk in the design.Should consider design according to different fire risks and distinct device for fire protection equipment, and should fully link up the back with the Fire Department of locality and confirm the safe and rational fire-fighting system.Environment compatibility: the construction of underground change should take into full account the planning of above ground portion, should with urban afforestation, public garage etc. auxiliary construction be set as far as possible.
