摘要
随着国家新能源基地的建成,甘肃风电基地将成为世界上最大的风电基地,但同时也面临着巨大的挑战。新能源基地风电主要面临的是输送能力、调频调峰、电力电量消纳和系统稳定四大问题。大规模风电的送出和消纳问题凸显,已直接影响到风电企业的效益和风电行业的发展。为保障新能源基地风电的稳定送出和有效消纳,结合甘肃电网的实际情况,针对甘肃河西地区新能源基地运行以来暴露的风电送出能力问题,分析了西北750 kV主网送出能力和330/110 kV电网就地消纳能力的主要影响因素,以及大规模风电外送对甘肃河西地区电网的影响,提出了提高输送能力和确保系统稳定的措施。
With the completion of the new national energy base, Gansu wind power project will be the largest wind power base in the world, however, it also faces enormous challenges. Those mostly lay on the four aspects： transmission capacity, peak load and frequency regulation, electricity accomodation and system stability. The highlighted issues of large- scale wind power transmission and accomodation have directly influenced the benefits of wind power companies and the development of wind power industry. In order to ensure the stable outward power transmission and active power accomodation in the new energy base, combined with the actual situation of the Gansu Power Grid, the issues are analyzed such as the main influenctial factors on the power transmission capacity of northwest 750 kV main grid and the local accomodation capacity of 330/110 kV power grid, as well as the impact of large-scale wind power outward transmission on the Hexi grid, based on the exposed problems of wind power transmission capacity in the Hexi area since the running of new energy base. Finally, the measures that could increase transmission capacity and ensure system stability have been proposed.
