广东电网天然气发电的相关问题及对策

Natural gas power generation related problems and its countermeasures for Guangdong power grid

广东省国民经济发展速度长期高于全国平均水平,电力需求的增长尤其迅速。广东省一次能源资源匮乏,加剧了供电紧张。按照国家部署,"十二五"到"十三五"期间有大量的天然气到达广东。天然气项目一般都要执行照付不议的合同,因此天然气发电对大型管道天然气项目和液化天然气项目有着重要的支撑作用。天然气发电具有环保、启停速度快等优点,因此,适当发展天然气发电不仅可以调整广东电网的电源结构、增加电力供应,而且有利于系统调峰。分析了广东天然气消费结构和发电能源结构,指出了在广东电网内天然气发电的优缺点及存在的问题,提出了广东电网在调峰需求下发展天然气发电的对策。

The development speed of economy in Guangdong Province is higher than the average level of the whole country. The power requirement also increases rapidly. There is lack of primary energy in Guangdong province which caused power supply shortage. According to the state＇s deployment, lots of natural gas will be sent to Guangdong during 2011 to 2020. Because natural gas project usually implements a take-or-pay contract, natural gas power generation is the most important support for large pipeline natural gas projects and liquid natural gas （LNG） projects. Natural gas power generation has the advantages such as environmental friendly, fast starting up and shutting down response. Hence appropriate development of natural gas power generation will not only adjust the power source of Guangdong power system, increase the power supply, but also benefit system peak shaving. The natural gas consumption structure and power source structure are analyzed. The advantages, disadvantages and the existing problems for natural gas power generation in Guangdong power system are indicated. The suggestion for developing natural gas power generation in peak shaving mode of Guangdong power system is proposed.
