摘要:
在电力需求日益增加而能源资源及负荷分布极不均衡的国情下,对特高压输电技术的深入研究和完善刻不容缓,其中特高压输电线路无线电干扰水平的准确评估和控制极为关键.目前特高压交流线路无线电干扰研究方法中使用较普遍的是激发函数法,该文采用一种更适合我国国情的激发函数对特高压线路无线电干扰进行研究,在2维模型的基础上用考虑弧垂的等效分析法进行了算例仿真,并与已运行的1 000 kV晋东南-南阳-荆门特高压交流示范工程线路无线电干扰实测数据进行对比,发现考虑弧垂的等效分析法更适用于实际工程,说明了实际特高压线路工程无线电干扰预测中考虑弧垂的必要性.最后分析了无线电干扰影响因素并提出了相应的减弱干扰措施,可为国家特高压输电线路以及杆塔的设计选型提供重要参考.
Abstract:
Under the condition of the increasing demand for electricity and the unbalanced distribution of energy resources and load,the Ultra High Voltage(UHV)transmission technology needs to be studied and improved urgently,and it's very important for the accurate evaluation and control of the radio interference from UHV transmission lines.At present,the method of the study on radio interference of the UHV AC transmission lines is usually the excitation function method.On the basis of a two-dimensional model,a typical simulation is performed used by the equivalent analysis method with the sag of the transmission lines.After comparing with the measured data from the 1 000 kV Jindongnan-Nanyang-Jingmen 1 000 kV UHV AC pilot project,it shows that the equivalent analysis method is more applicable to the practical engineering.The results of the paper suggest that it's necessary to consider the sag in the prediction of radio interference in the practical UHV transmission project.Finally,the influence factors on the radio interference are analyzed and the corresponding solutions are given to weaken the interference,which are helpful for the design and selection of UHV transmission lines and towers.
