摘要

为保证天然气管网能量计量的可靠性,以浙江省天然气管网为研究对象,基于管段压差与流量的水力关系,考虑了天然气管网的局部特性,建立了天然气管网局部能量赋值算法。基于所建立的天然气管网局部能量赋值算法,对浙江省杭州站、永康站及下沙站的天然气管能量进行了赋值计算,并将计算结果与测量值进行了对比,计算值与测量值相对误差控制在0.6%以内,符合OIML R140和GB/T 18603-2014中关于计量站赋值发热量的最大允许误差应不超过0.6%的A级规定。

Abstract

In order to ensure the reliability of energy metering for the Zhejiang natural gas pipeline network, a local energy assignment algorithm was established. The assignment algorithm was based on the hydraulic relationship between the pressure difference and flow quantity of a single pipeline, and taking into account the local characteristics of natural gas pipeline network. By using the established local energy assignment algorithm, the natural gas pipeline energy of Hangzhou Station, Yongkang Station and Xiasha Station in Zhejiang Province was calculated, and the calculated results were compared with the measured values. The relative error between the calculated values and the measured values was within 0.6%, it met the criterion in the provisions of OIML R140 and GB/T 18603-2014 Technical Requirements, indicating the reliability of the assignment algorithm, and providing guarantee for the natural gas transaction, where the criterion requires the maximum permissible error of energy metering of assignment algorithm should within 0.6%.
