| This article are done analysis, comparison, calculation and reasoning through the Fertilizer Plant of Jilin Petrochemical Company. It has been running more than30years and has many hidden dangers of the primary substation system, to find out main problems restricting of substation’s running. It put forward the feasibility of the governance solution, including the system a part of the hidden danger management and energy-saving renovation scheme of technical and economic comprehensive analysis, make the necessary electrical calculation and the related electrical equipment parameters require combining the development and application of advanced technology at home and abroad.System secondary relay part of protection and safety automatic devices is put forward, the phase Angle measurement device, automatic scheduling, anti-fuzzy station, electric energy metering device and electric energy remote terminal, terminal power generation side offer, system communication access scheme.It has designed for transmission lines, substation upgrading and investment estimation, networking scheme of electricity transmission&transformation facilities parts to line, line spacing of the substation involved.lt carries on the system analysis through analyzing existing distribution system integrated automation technology, the selection of design conditions, secondary system of technical analysis and Sepam series technology, integrated substation protection engineering overall vision, feasibility and assume the main electrical wiring scheme comparison. And this has been a substation the retrofit scheme of the system more perfect.This can make the primary substation system better in functionality and stability and anti-interference performance, eliminate safety hidden danger affecting the operation of a longer period. |
