摘要:

西北地区新能源接入主要受西北—新疆联网通道输电能力的影响和限制,为合理规划发展西北地区新能源,对新能源接入与西北—新疆联网通道输电能力及系统安全稳定性进行了研究。采用PSD-BPA机电暂态仿真程序,分析了新疆哈密地区风电、甘肃河西走廊地区风电、甘肃金昌等地光伏电源以及青海柴达木地区光伏电源接入后,对西北—新疆联网通道输电能力及系统安全稳定性的影响。结果表明:哈密风电接入规模及风电机组控制方式对西北—新疆联网通道输电能力的影响不大,但哈密风电接入会降低系统的安全稳定水平;而甘肃风电及光伏电源的接入有利于西北—新疆联网通道输电能力及系统安全稳定水平的提高;青海地区光伏电源的接入会使西北—新疆联网通道输电能力下降,且使西北—新疆联网第一通道安全稳定性下降,但会使总的新能源接入规模得到大幅提高。根据分析结果,建议合理发展青海、甘肃光伏电源规模,并注意发展比例。同时,在发展大规模风电及光伏电源的同时,应注意西北—新疆联网通道安全稳定控制措施的合理制定。

Abstract:

  The integration of Northwest renewable power resources in Northwest area is mainly restricted by the transmission capability of the Northwest-Xinjiang power corridor. In order to make reasonable development planning of the Northwest renewable power resources, this paper studies the relations of the integration of renewable power resources to the transmission capability of the Northwest-Xinjiang power corridor and the power system's security and stability. We adopt PSD-BPA electromechanical transient simulation program to analyze the impact of wind power integration in Xinjiang Hami, Gansu Hexi Corridor and PV power integration in Gansu Jinchang, Qinghai Qaidam on the transmission capability of the Northwest-Xinjiang power corridor and the power system's security and stability. The results indicate that the Hami wind power's integration and the Hami wind power units' control mode have small influence on the transmission capability of the Northwest-Xinjiang power corridor, but the Hami wind power's integration will decrease the power system's stability; the Gansu wind power and PV power's integration will increase the transmission capability of the Northwest-Xinjiang power corridor and the power system's stability; the Qinghai PV power's integration will decrease the transmission capability of the Northwest-Xinjiang power corridor and the stability of the first corridor of the Northwest-Xinjiang power corridor, but the total integration amount of the renewable power resources will be greatly increased. According to the analysis results, it is suggested that the development scale and the scale ratio of the Gansu and Qinghai PV power resources should be reasonably made, and the development proportion should be paid attention. Meanwhile, the suitable security and stability control measures should be made when the power system has large scale wind power and PV power's integration.

Key words:  wind power, PV power, Northwest-Xinjiang power corridor, transmission capability, security and stability
