Work Detail

Solar Photovoltaic Modules – Construction Of Two Photovoltaic Installations At The Zawada Power Plant In Zielona Góra. The Subject Of This Order Is The Construction Of A Photovoltaic Installation At The Zawada Water Treatment Station In Zielona Góra, Divided Into Two Stages, According To The Design Documentation: 1) Construction Of A Photovoltaic Installation With A Capacity Of Up To 160 Kw At The Zawada Water Treatment Station In Zielona Góra. The Photovoltaic Installation Will Be Connected To The Existing Rg In The Existing Transformer Station Building. Due To The Location And The Amount Of Connection Power, The Designed Photovoltaic Installation Will Consist Of The Following Elements:  286 Photovoltaic Cells On Supporting Structures, 3 Inverters With A Total Rated Power Of 150 Kw,  Direct Current Electrical Installation,  Three-Phase Alternating Current Electrical Installation. 2) Construction Of A Photovoltaic Installation With Power Up To 560 Kw Along With An Energy Storage With A Capacity Of 1,290 Kwh At The Zawada Water Treatment Plant In Zielona Góra. The Photovoltaic Installation Will Be Connected To The Existing Rg In The Existing Transformer Station Building, Through The Designed Rn-W Connector. The Energy Storage Facility Is Designed As A Prefabricated Container Structure Consisting Of The Following Elements: • Concrete Housing Of The Storage Facility With A Transformer Chamber, • Prefabricated Concrete Foundation, • Lv And Dc Switchboards, • Bidirectional Ac/Dc Converter, • Sps-Kontrol Control System, • Fire Extinguishing System. • Energy Storage, • Transformer, • Concrete Roof. Technological Data Of The Station: • Lighting, • Gravitational + Mechanical Ventilation, • Air Conditioning, • Louvered Inlet And Outlet Openings Located In The Rear Wall, Side Wall And Doors, • Grounding Installation. The Designed Photovoltaic Installation, Due To Its Location And The Amount Of Connected Power, Will Consist Of The Following Elements: • 1,014 Photovoltaic Cells On Supporting Structures, • Inverters With A Total Rated Power Of 500 Kw In Quantity 5 Pcs. • Direct Current Electrical Installation • Three-Phase Alternating Current Electrical Installation 3) Development Of Design Documentation And Reconstruction Of The Installation In Accordance With The Connection Conditions - Stage Ii By Making Connections To The Lv Switching Station Network And Reconstruction Of Power Connections Of The Mv Gpz Zawada Station: • Development Of Design Documentation Along With Making All Necessary Arrangements And Notifications, Obtaining All Required Permits For Implementation And Preparation Of As-Built Documentation, Reconstruction Of The Installation In Accordance With Connection Conditions - Stage Ii: • Extension Of Two Mv Cable Lines By Approx. 15 M With Introduction To Prepared Power Supply Fields, • Reconstruction Of Fragments Of Two Overhead Lines Into Cable Lines With A Length Of Approx. 50 M, Liquidation Of One Pole, • Replacement Of Two Poles With Vibrated Ones With Built-In Disconnectors, • Introduction Of Rebuilt Mv Lines To Prepared Power Supply Fields. Both Photovoltaic Installations Are Intended To Convert Electricity
