摘　　要：针对专用工程接入电网收费现状,探讨了利用接入费和使用费收取专用工程的投资成本与运行维护成本的方法。从可靠性角度出发,提出了考虑深度回收机制的接入费用收取模式,主要是针对因用户接入而造成的网络扩容时间提前产生的成本。利用配电网节点支路—灵敏度系数矩阵结合支路电流边际容量成本,形成节点边际容量成本,评估用户在该节点接入时应该支付的深度成本,并引用某一实际配电网专用接入工程进行了分析计算,验证了该方法的合理性。According to the current situation of specialized transmission project charges, the investment cost and operation maintenance cost can be repaid by connection and use fees. A novel charge pattern of connection fee considering deep recovery mechanism is proposed from reliability point of view. The pattern considers not only project investment cost, but also extra cost of other user’s reliability in distribution network. The extra electrical equipment expansion cost is caused by connection of specialized transmission project. Depending on node and branch sensitivity coefficient matrix and branch current marginal capacity cost, the locational marginal capacity cost is calculated to evaluate deep cost associated with the connection of specialized transmission project. The proposed method is applied to a practical specialized transmission project. The testing results verify the validity of proposed method.
