电力电网
电(dian)(dian)(dian)(dian)力体系的(de)主体布局有电(dian)(dian)(dian)(dian)源（水电(dian)(dian)(dian)(dian)站、火电(dian)(dian)(dian)(dian)厂(chang)、核(he)电(dian)(dian)(dian)(dian)站等发电(dian)(dian)(dian)(dian)厂(chang)），变电(dian)(dian)(dian)(dian)所（升压变电(dian)(dian)(dian)(dian)所、负荷中间(jian)变电(dian)(dian)(dian)(dian)所等），输电(dian)(dian)(dian)(dian)、配电(dian)(dian)(dian)(dian)线路和负荷中间(jian)。各电(dian)(dian)(dian)(dian)
源点还相(xiang)互连接以完成差别地(di)域之间的电能互换和(he)调理，从而进(jin)步(bu)供电的宁静性和(he)经济性。
