Analysis of Power Distribution Reliability in Henan Oilfield Refinery and Measures

Re1iability of power distribution is the key to safeproduction in refining and chemical engineeringenterprises. The main factors that influence powerdistribution reliability in Henan Oilfield Refinery areana1yzed based on the stutistics of power distribution inthe last three years. They mainly include the voltage gradeof the refinery being low and the refinery sharing powerwith other consumers. It is practicab1e to supp1y powerwith double-source and is necessary to set up a l1Okvtransformation station in the refinery. Some othersuggestions to improve power distribution reliability arealso inc1uded in this paper.
