风电汇集地区次同步振荡控制系统的研究
|
摘要
电力电子设备的广泛应用使得电力电子化系统的振荡问题凸显,电网安全运行控制面临着更加严峻的挑战。文中基于风电汇集地区出现的次同步振荡问题,通过对新疆哈密风电运行情况以及次同步振荡产生机理进行分析,提出了次同步振荡控制系统的三道防线,并将该控制策略应用到哈密望洋台地区进行现场试验。实验结果表明:次同步振荡系统能够准确的切除风电场振荡线路,初步判断出振荡源,从而保证了控制系统的灵敏度和可靠性。
Extensive applications of power electronic equipment bring more significant oscillation to power elec-tronic systems, resulting in serious challenges to security operation of power grid. In this study, according to the subsynchronous oscillation problem emerged in wind power integration areas,the wind power operation and the mechanism of subsynchronous oscillation in Hami,Xinjiang were analyzed,three lines of defense of subsynchro-nous oscillation control system were established,and the control strategy was tested in the certain wind power ar-ea in Wangyangtai,Hami. Experimental results show that the subsynchronous oscillation control system can accu-rately remove the oscillating circuit of wind farm,preliminarily determine the source of oscillation,and ensure the sensitivity and reliability of the control system.
