关于交流10kV配电网多种改造方案的性能对比分析
|
摘要
应对现有10kV交流配电网存在的供电不足,供电走廊紧张,损耗严重和不易接入分布式电源等问题,提出10kV交流和±10kV直流混合配电、±10kV单母线直流配电电压等级和±10kV与低压±440V的双母线直流配电电压混合三种改造方案。以IEEE10结点为基本框架,就供电能力、运行效率和经济性,对三种方案进行对比分析。首先对交、直流配电网的供电能力进行简要分析;然后分析了采用不同方案时总负荷、供电半径和直流负荷比率对运行效率的影响;最后比较三种方案的经济性。最终综合考虑得出最佳的改造方案。
Deal with a variety of problems of the existing 10 kv ac power distribution network, the paper puts forward 10 kv ac and +10 kv dc hybrid power distribution, plus or minus 10 kv single busbar dc power distribution voltage grade, and plus or minus 10 kv double bus with low voltage + 440 v dc distribution voltage hybrid three retrofit scheme, the power supply is the main ability, efficiency and economical efficiency of these schemes are analyzed.In this paper, IEEE14 is the basic framework, and the three schemes are compared and analyzed.Firstly, the power supply capacity of ac and dc distribution network is analyzed briefly.Then the influence of total load, power supply radius and dc load ratio on operation efficiency is analyzed.Finally, the economy of the three schemes is compared.Finally, the best reconstruction plan is considered.
