摘要
大量的高能耗配电变压器在我国配电网中使用,造成配电网能量损耗巨大,用节能型的低能耗变压器取而代之,是电力网实现经济运行的重要途径。就节能变压器取代高能耗配电变压器的经济效益问题,建立了基于运行风险的变压器更新经济效益评估模型,充分考虑了变压器更换后的各种减免投资和风险效益。通过仿真计算可以看到,更换老旧变压器的节电效果明显,经济效益可观。
High energy-consuming distribution transformers are widely used in power distribution networks, which causes large energy losses in distribution systems. Replacing the old transformers with energy-saving ones is the key way to realize economic operation of power networks. An economic evaluation model of distribution transformer updating based on risk assessment is built to measure economic benefits thoroughly considering a list of decreasing investment and risk earning. Simulation shows that high energy-consuming transformer updating has obvious energysaving effect and considerable economic benefits with an approximate 10 years＇ payback period.
