Tenders Are Invited For Transformer Substation – Modernization Of The Command-Control-Protection-Metering System 220 Kv, 110 Kv In The 220/110/20 Kv Station And Medium Voltage Refurbishment And Internal D.C. And A.C. Services In The 220/110/20 Kv Ghizdaru Station

Transformer Substation – Modernization Of The Command-Control-Protection-Metering System 220 Kv, 110 Kv In The 220/110/20 Kv Station And Medium Voltage Refurbishment And Internal D.C. And A.C. Services In The 220/110/20 Kv Ghizdaru Station. The 220/110/20 Kv Ghizdaru Electrical Substation Is Located In Stănești Commune, Giurgiu County. It Was Put Into Operation In 1974 And Represents An Important Node Of The National Energy System, Regarding Both The Supply Of Electricity To The E-Distribuție Muntenia Distribution Network In The Area, But Also To Allow The Connection Of New Producers Of Electricity. The Passage Of Time, The Completion Of The Life Span, Have Led To Increased Physical And Moral Wear And Tear Of The Secondary And Partially Primary Elements Related To The Equipment In The Station As Well As Those Related To The Internal Services. During The Operation Of The Station, A Series Of Malfunctions Resulted, Which Led To High Expenses And Low Performance From A Technical Point Of View. From The Point Of View Of The Protections And Secondary Circuits, There Have Been Erroneous Functionings Of The Protections Or Defects In The Secondary Circuits That Have Determined Repeated Interventions By The Maintenance And Maintenance Personnel. For These Reasons, It Is Necessary To Modernize The Protection Installations From All Elements (220Kv, 110Kv, 20Kv And Internal Services) But Above All To Create A Modern Scada System, In Accordance With The Latest Ntis Of Transelectrica, Which Ensures The Remote Control Of The Entire Station From The Level The Telecontrol Center Of Stt Bucharest And The Central And Territorial Dispatch Centers, In Order To Meet The Current Functional And Operational Safety Requirements Of Sen. The Purpose Of The Contract Is To Provide Products, Services And Works Necessary For The Implementation Of The Contract Modernization Of The Command - Control - Protection - Metering System 220 Kv, 110 Kv, In The 220/110/20 Kv Substation And The Medium Voltage Refurbishment And Internal Services D.C., A.C. In The 220/110/20 Kv Ghizdaru Station. As Part Of The Contract, All The Products (Equipment, Materials) Will Be Supplied, The Services Will Be Provided (Design, Engineering, Configuration, Parameterization, Testing, Training, Integration, Etc.) And The Assembly Works Necessary For Putting The New Products Into Operation Will Be Performed, In In Accordance With The Requirements Of The Specifications. In Summary, The Following Are Included In The Scope Of The Project: - The Replacement Of 4 Sets (4 X 3 Single-Phase Pieces) Of 220 Kv Separators With Two Clps, As Follows: Sb 1 (Ct Cell), Sl (Lea Turnu Măgurele Cell), Sat (Cell At1), Sl (Cell Lea Bucharest Sud 2). -Installation Of Connection Boxes For Current/Voltage Measurement Transformers, In All 220 & 110 Kv Cells, Where None Existed In The Existing Situation, -Renovation Of The 20 Kv Station, Including Adaptation And Rehabilitation Works Of The 20 Kv Connection Building -Renovation Of The D.C./C.A. Own Service System - Modernization Of The Control System, Control, Protection Measure At All Voltage Levels - Construction Works In The External Station - Construction And Installation Works In The Control Block Building, As Well As In The Diesel Group Building - Temporary
