Implementation of Variable Speed Drive for Oil-Pump System

Abstract:

This paper presents a study of efficiency improvement in the oil pipeline system. Instead of using only control valve, the original system of two oil pumps which have rating of 1,850 kW each is redesigned by using variable speed drive (VSD) technology together with the control valve. This proposed installation method of VSD will be performed to adjust and open the control valve fully at 100%. Furthermore, the frequency control method of the VSD also depends on types of oil. In the efficiency analysis of the oil pipeline system, four types of oil that is JET A1, Disel, B91, and B95 having different density coefficient will be used respectively. The new and the original data acquisition of relationships between transported oil quantity of each type per period and consumed power are compared. From the sequent results, it can be confirmed that this proposed method used to the practical analysis in accordance with Affinity Law can be applied to not only improve the efficiency and also save cost of the power consumption up to 42.96%.
