Anti-icing method for overhead wire based on real time operation mode

一种基于实时运行方式的架空线抗凝冰方法

Abstract

本发明涉及一种基于实时运行方式的架空线抗凝冰方法,属于电力系统调度自动化领域,该方法包括:利用电网能量管理系统实时采集的电力系统运行状态,通过状态估计得到电力系统实时网络拓扑和实时潮流;根据架空线的凝冰情况,在保证系统动态稳定的前提下,通过改变实时运行方式,加大凝冰风险大的线路的功率输送,利用导线的电阻产生更大的热量从而螎化或阻止线路覆冰。这种抗凝冰方法利用了电网调度自动化系统,不需要或新增少量设备即可达到抗凝冰目的,成本低、实施方便。
The invention relates to a deicing method for an aerial line, which is based on a real-time running mode, and belongs to the automation field of electric power system management. The method comprises the following steps: an electric network power management system is utilized to collect the running states of the electric power system on a real-time basis, and the real-time network topology and real-time current of the power system are obtained through state estimation; on the premise that the system dynamic stability is guaranteed, the power transmission of the line at high icing risk is increased according to the icing condition of the aerial line, so as to utilizing the resistance of the line to produce more heat and thaw ice or prevent the line from icing. The deicing method utilizes the electric network management automation system without the need or with little need of few apparatuses, the cost is low, and the implementation is convenient.
