Our Company Petronet MHB Ltd (PMHBL), Bangalore, India operates a 363 Km multi petroleum product cross – country underground 24”/20” diameter pipeline having two terminal plants and 3 pumping stations, 10 SV stations, 3 BV stations and 1 IP station. PMHBL is an ONGC subsidiary with HPCL, two leading public sector oil companies of India. The objective of our solution was to design, implement, and operationalize a fully unmanned Sectionalized Valve station with a self-sustained, intelligent power system eliminating dependency on conventional Electricity Board /Diesel Generator. This also aimed to reduce fire hazards, human error, and carbon footprint while enhancing remote operability and resilience. Sectionalizing Valve (SV) stations are critical infrastructure in petroleum pipeline networks for isolation, pressure control, and emergency mitigation. Traditionally in India, SV stations are manned round-the-clock and powered by primarily EB (Electricity Board) and secondary as DG (Diesel Generator) sets, increasing operational costs, safety risks, and environmental impact. With implementation of Unmanned SV Station Powered by Hybrid Renewable Architecture we have completely eliminated Human interference and completely automated operational system by A two-tier hybrid power system comprising: 1. Primary Power from Solar PV 2. Secondary Power via Lithium Ferro Phosphate (Lifepo4) Battery Energy Storage System (BESS) Hybrid solar system A two-tier hybrid power system was developed comprising: 1.Primary Power from Solar PV 2. Secondary Power via Lithium-ion Battery Energy Storage System (BESS) The BESS is charged through solar system The power system is managed through Hybrid inverters of different output voltages viz 3 Phase/ 1Phase AC & 48v DC, enabling seamless switching between sources. High power consumption Legacy lead acid battery banks, battery charger panels for CP (Cathodic Protection), Telecom systems were decommissioned. A unified AC/48V DC bus system was implemented to power all critical equipment with isolated protections for each system, automatic PF control and eliminate power hormonics
