田湾核电站7、8号机组柴油发电机设置原则及合并可行性分析

Setting Principle and Combination Feasibility Analysis of Diesel Generators of Units 7 and 8 in Tianwan Nuclear Power Station

田湾3、4号机组常规岛每台机组设置两台6100 kW柴油发电机,文章根据列宁格勒-2核电站的设计实践(已经实施两台机组柴油发电机合并为一台的设计方案)来进行分析,论证田湾7、8号机组机组柴油发电机的设计方案。方案从设置原则、容量对比、优劣性分析等几个方面展开,并进行了经济技术分析比较。经过初步负荷加载计算,机组柴油发电机合并从技术上是可行的,在经济上具有明显优势。

Two 6100 kW diesel generators had been installed for each unit on the conventional island of units 3 and 4 in Tianwan Nuclear Power Station.Based on the design practice of Leningrad Phase II Nuclear Power Plant(the design scheme in which the two diesel generators have been combined into one),this paper analyzes and demonstrates the design scheme for the diesel generators of units 7 and 8 in TNPS.The scheme is carried out from several aspects such as setting principle,capacity comparison,advantages and disadvantages analysis,and economic and technical analysis and comparison.After preliminary load calculation,the combination of diesel generators is technically feasible and economically advantageous.
