Research Progress on Calculation and Control of Unaccounted for Gas of Natural Gas Pipeline Network

Abstract At present, volume measurement is still used in transfer of natural gas China, so the calculation and management Unaccounted for Gas are based on measurement. With change method from to energy measurement, will be paid more attention. This paper investigates methods measures China other countries, compares research progress. The results show that: general principles countries basically same, but formulas not completely same. All consider input gas, output line pack variation self-consumption gas. On this basis, Italy considers known leakage, Britain leakage daily calorific value shrinkage caused by its settlement rules. In order reduce Gas, UK regularly verifies meter, carries out baseline, actively participates global benchmarking. Australia replaces old main reduces operation pressure pipeline, which significantly Gas. control Italy, can reference China.
