Analysis and Comparison of Power Supply Schemes for well Clusters in Gas Gathering and Transmission Engineering

Based on load specification, the power supply model and requirement of well clusters is presented and established in gas gathering and transmission engineering, which is applied on type I and type II. The study considers both reliability and economy of all power supply proposals, and comparatively calculates and analyzes the numbers and types of main electrical equipments, capital expenses (CAPEX) and operating expenses (OPEX). Specially, for the problem of voltage drop, it illustrates the contrast and selection of power transformers with two ratings by the technical features of standard. Finally, the paper respectively puts forward the power supply schemes for well clusters type II and type II from different proposals based on the detailed results, which shows that the conclusions are feasible and reasonable in the practical engineering application.
