随着我国电力建设的高速发展,电网的容量越来越大,输电距离越来越长。出于电网运行安全、稳定、经济等方面的需要,我国正在加紧规划和建设大型抽水蓄能电站。已建成的北京十三陵和广州等抽水蓄能电站,在电网安全、稳定、经济运行等方面已经取得了良好的效果。随着我国西部大开发及“西电东送”工程的实施,必将会同时迎来我国较大规模的抽水蓄能电站建设高潮。 1各类发电厂的能源转换过程及抽水蓄能电站的能源转换特点 1.1各类发电厂的能源转换过程
With the rapid development of China’s power construction, the capacity of the power grid is getting bigger and bigger, and the transmission distance is getting longer and longer. Due to the needs of grid operation safety, stability and economy, China is stepping up its planning and construction of large-scale pumped storage power stations. The completed pits such as the Ming Tombs in Beijing and pumped storage power plants in Guangzhou have achieved good results in terms of power grid security, stability and economic operation. With the great development of western China and the implementation of the “West to East Power Transmission” project, it will surely welcome the climax of the construction of larger-scale pumped-storage power stations in our country at the same time. 1 Energy Conversion Process of Various Power Plants and Energy Conversion Characteristics of Pumped Storage Power Plants 1.1 Energy Conversion Process of Various Power Plants
