南方地区天然气分布式能源系统特点和发展对策研究

Study on the Characteristics and Development Strategies of Natural Gas Distributed Energy System in Southern China

摘要: 本文基于可持续发展的需要，针对我国南方地区的能源资源情况、能源消费结构、以及气候和区域特点，从能源技术和能源发展战略的角度，研究了南方地区天然气分布式能源发展对策和模式。研究结果表明，我国南方地区能源资源紧缺，用电用气负荷的季节性差别较大，但随着国家天然气管网的发展以及非常规天然气的开发，供气能力不断增强，天然气分布式能源技术和市场条件不断成熟，在发展天然气分布式能源时应优先选择工业园区和新建建筑，示范推广后，再在其他区域或既有建筑上推行；在能源项目建设时应坚持以起源供应确定项目布局，以能源利用效率最大化原则指导设备选型，以冷热负荷需求确定系统容量和规模。天然气分布式能源的科学有序发展，将为南方地区经济和社会的发展提供强大的保障和动力。

Abstract: Based on the analysis of energy resources, energy consumption structure, climate characteristics and regional characteristics of southern China, the strategies and models of energy development of southern natural gas utilization were studied through the review of energy technology and energy development strategy. Results show that in southern China, according to the current condition, natural gas distributed energy system should be developed preferentially in industrial zones and new buildings. After being exemplarily operated and optimized, it can be applied to some other regions or existing buildings. To develop natural gas distributed energy projects, some principles should be insisted on. Such as determining the project layout by the origin of the supply, guiding the equipment selection by principle of energy efficiency maximization, determining the system capacity and scale by the demand for cooling and heating load. Scientific and orderly development of the natural gas distributed energy will provide strong protection and power for economic and social development of the southern.
