中文摘要：
西气东输二线工程是我国第一条引进境外天然气的大型管道工程,是我国油气资源多元化供应战略的具体体现,未来30年内,我国每年将从中亚引进300亿m3天然气。我国已经明确了优化发电能源结构、发展清洁能源发电的战略,天然气是清洁能源,适当发展天然气发电不仅能够改善电源结构,还能够提高电力工业效率和降低污染物排放,但是目前我国天然气发电市场和相关产业政策体系尚待完善。本文分析了发展天然气发电面临的主要障碍,并以珠三角地区某电厂为研究对象测算了天然气发电的经济性和对西二线天然气价格的承受能力,以经济性测算结果为依据,从电价、气价、税收、电网调度、天然气交易模式等方面提出了政策建议,希望能够为西二线天然气发电的发展和国家重大能源战略的落实提供辅助支持。
英文摘要：
The Second West-to-east Gas Pipeline is the first large pipeline project importing oversea natural gas to China. It is also the embodiment of the strategy of energy resource diversification in China. In the future 30 years, China will import 30 billion ms of natural gas from central Asia through the 2na West toeast gas pipeline every year. China has set up the strategy of improving the structure of power generation energy resources and developing clean power. As clean energy, gas for power will not only improve power generation structure but also reduce emissions. However, the electricity market and the related industrial policies are still immature. This paper analyzes the main obstacles of developing gas power generation and makes a financial analysis on a typical gas plant in Guangdong. Based on the calculation results, this paper puts forward several suggestions from the perspective of electricity price, gas price, tax policy, dispatching mechanism and trade mode of natural gas for power generation. The research aims at providing decision support for the development of the 2nd West-to-east gas for power generation and the implementation of the national energy strategies.
