|
摘要
为降低电能替代下城市配电网的配电变压器运行损耗,根据有载调容配电变压器和常规配电变压器的损耗关系推导出有载调容配电变压器更换判据,获得有载调容配电变压器可更换点集合,实现了有载调容配电变压器更换常规配电变压器的初步判断。然后基于有载调容配电变压器更换成本效益分析,建立了电能替代下的城市配电网有载调容配电变压器规划模型,并采用分支定界法在有载调容配电变压器可更换点集合内求解该模型,从而得到电能替代下的城市配电网配电变压器最优规划方案。最后,对某城市配电网电能替代点进行配电变压器规划,以验证该方法的可行性。
To reduce operation loss of distribution transformers in urban distribution network after electric energy substitution, this paper proposed a criterion of replacing with on-load capacity regulating distribution transformers, according to the relationship between conventional distribution transformer loss and on-load capacity regulating distribution transformer loss. And the distribution transformer replaceable point set was obtained, realizing preliminary judgment of replacing conventional distribution transformers with on-load capacity regulating distribution transformers. Then, based on cost-benefit analysis, the planning model of on-load capacity regulating distribution transformers in urban distribution network after electric energy substitution was established. The model was solved by branch and bound method within distribution transformer replaceable point set, so as to obtain optimal distribution transformer planning scheme. Finally, the distribution transformer planning of substitution points in an urban distribution network was carried out to verify the feasibility of this method.
