Offshore oil-gas platform group natural gas interactive scheduling method

Abstract

The invention relates to a natural gas interactive scheduling method for an offshore oil and gas platform group. The method comprises the steps of obtaining a natural gas network topology structure and a power grid topology structure of the offshore oil and gas platform group; acquiring design parameters and operation parameters of key equipment of a natural gas system and key equipment of a powersystem of the offshore oil-gas platform group; establishing an optimization model of the interconnected power system according to the design parameters and the operation parameters, determining an objective function to be minimum in natural gas self-consumption of all turbine units and minimum in unit pollutant emission penalty cost, and determining constraint conditions; establishing an optimization model of the interconnected natural gas system according to the design parameters and the operation parameters, determining that an objective function is the minimum sum of all torch emptying amounts and the minimum overall pollutant emission penalty cost of the system, and determining constraint conditions; and solving the two optimization models, wherein a solving result is used for realizing interactive scheduling of the natural gas pipeline network. The energy consumption of the offshore platform can be reduced, the energy mutual assistance between the platforms is improved, and the energy supply stability of the platform group is improved.

Description

technical field [0001] The invention relates to the technical field of energy comprehensive utilization optimization of offshore oil and gas platform groups, in particular to a natural gas interactive scheduling method for offshore oil and gas platform groups. Background technique [0002] Offshore oil and gas platform is an important work platform for exploiting seabed mineral resources, and its energy power system safety and stability has always been the focus of research. The traditional offshore oil production platform is an isolated system. The platform meets the power demand of the platform through its own associated gas and crude oil. Due to the limitation of the space size of the platform and the energy conversion efficiency of the power generation equipment, the platform generally uses multiple micro gas turbines to generate electricity in parallel. A single platform The power generation efficiency is not high, and the thermal backup is large. The energy management ...

The traditional offshore oil production platform is an isolated system. The platform meets the power demand of the platform through its own associated gas and crude oil. Due to the limitation of the space size of the platform and the energy conversion efficiency of the power generation equipment, the platform generally uses multiple micro gas turbines to generate electricity in parallel. A single platform The power generation efficiency is not high, and the thermal backup is large. The energy management system mainly focuses on the stable operation of the power grid, and seldom considers optimal scheduling
