South Yard Substation Commissioning – Largest electrical upgrade project in refinery history. 50+ Medium Voltage breakers, 120+ SEL protective relays, four power transformers, SCADA system and associated switchgear and station equipment.
Our scope of work included:
developing the commissioning plan, and all test plans to include protection & SCADA, and to execute the testing of all equipment. We developed satellite synchronized end to end functional tests of the line differential protection schemes; one of these schemes includes a three terminal line differential scheme. Power Pros was the first and remains the only company to perform End to End testing at the Chevron Richmond refinery. As a result of the successful implementation and execution, this technique has been adopted by other Chevron refineries and is now standard procedure for electrical commissioning projects at Chevron.
