Study Of Substation Project Planning Based On LCC And Its Application System Design

With the deepening of China’s industr ia lization a nd urbanizatio n, the natio na lecono my is being steady a nd rapid deve loped whic h dr ives the dema nd for powercontinues to grow. In order to meet the growing dema nd of power a nd thedevelop me nt o f s mart gr id, power compa nies are investing b illio ns o f do llars inconstructio n o f power gr id. And substation project occupies a cons iderableproportion o f the huge power project investment. There fore, the mana ge me nt le ve lof s ubstation project p la nning a nd des ign natura lly becomes o ne o f the key factorswhic h decide the core competitiveness o f power co mpan ies.The top ic this artic le se lected root in the key scie ntific research projects ofSGCC (State Grid Corporation o f China), whic h na med "The Research on The NewTechno logy about Who le Life Cyc le Des ign of S ubstation Project ". The method ofthis research focuses on long-ter m economic bene fits of equip me nt or syste m,cons idering its who le process inc lud ing p lanning, design, manufacture, purc hase,insta llatio n, operatio n, ma intena nce, mod ificatio n, renewa l a nd the scrap, whic hwould satis fy the re liab ility a nd other req uire me nts o f the sys te m and optimize thesubstation project cost and impro ve the resource utilizatio n o f powe r enterpr ises atthe sa me time.First of a ll, according to the character istics o f the substatio n project as well asthe LCC ma na ge ment theory, the artic le d issected the composition o f the substatio nproject, and severa l key factors whic h would affect the LCC of substatio n project hasbeen carr ied on the detailed ana lys is.Next, the paper stud ied the ge nera l estimatio n methods for project LCC,ana lyzed the app licab ility of var io us estimation methods in d ifferent stages of thewho le life cyc le, and put for ward severa l correctio n processing.The n, the artic le deve loped estima tion mode l fro m the perspective o f the flowof power, whic h inc ludes the ma in body as well as high-med ium-low vo lta ge sideoutlet o f the substatio n. The estima tion mode l pro vides qua ntitative data support forpla nning and eva luation of the project. Comb ined with the typ ica l design data andecono mic a nd technica l parameters o f constr uctio n operatio n for tra ns for mer andcirc uit, the paper ver ified the correctness and practicability of the proposed mode lthro ugh ana lyzing a project insta nce. In additio n, the artic le a lso has carr ied on the sens itivity ana lys is to design sche me, get the best va lue of capacity and the Numbersof substatio n ma in tra ns for mer under different load rate, whic h would providerefere nce for substatio n project pla nning.Fina lly, on the bas is of the theory o f full te xt research, the artic le deve loped"S ubstation Project Life-Cyc le Des ign Optimiza tion and Dec is io n-Making Syste m "based on the concept of LCC, and deta iled ly des igned the modules o f syste m’sovera ll fra mework, data ma nage me nt, data a na lys is and graphics d isp lay,innovative ly introduces OpenGL tec hno lo gy in the graphica l disp la y mod ule torealize the dyna mic disp la y for the des ign process of the substatio n project.
