“煤改电”工程用电采暖替代企业和居民的冬季燃煤取暖，可以有效促进大气污染的治理工作。以北方某地区的农村配电网为例，在深入分析低压配电网现状问题的基础上，结合一个深山区农村“煤改电”试点工程，对使用家庭电采暖的农村低压配电网建设工作进行了研究，提出了规划与改造的基本思路和方法，给出了规划电采暖的用电负荷和评价指标。经过试点工程的应用，验证了规划方法的实用性和有效性。%Coal-to-electricity project aims to replace coal-burning stoves for industrial and residential purposes with electric ones. Taking rural distribution network in certain area of North China for example, on the basis of analyzing the present low-voltage distribu-tion network status, this paper studied the construction of the rural low-voltage distribution network for the home application of electric heating facilities by combining with the rural coal-to-electricity demonstration project in a remote mountain area. The basic planning and reconstructing idea method were presented and the load index of electric heating and the evaluation index in plan were given. The practicability and effectiveness of the method are verified through the practical engineering application of the demonstration project.
