摘要

近年来中国风电的迅猛发展对地区电网的送出能力提出了更高的要求

亟需采取合理措施提高地区电网的风电送出能力

以缓解弃风问题、促进可持续发展。统一潮流控制器具有强大的潮流控制功能

有助于解决上述问题。文中分析了统一潮流控制器应用于提高地区电网风电送出能力时的基本控制模式

结合限制风电送出的主要因素

给出了统一潮流控制器的适用场景及选址定容的原则和方法

并进一步提出了统一潮流控制器的控制策略。最后结合云南楚雄地区电网算例

通过潮流计算和暂态仿真

验证了前述方法和策略的有效性。计算结果表明

通过加装统一潮流控制器

可以大幅提高楚雄地区的风电送出能力。

Abstract

In recent years

the rapid development of wind power in China has put forward higher requirements for the transmission capacity of power grid. It is urgent to take reasonable measures to improve the wind power transmission capacity and alleviate the abandonment of wind

the basic control mode of unified power flow controller（UPFC）is analyzed when it is applied to improving the wind power transmission capacity. Considering the main factors that restrict wind power delivery

the applicable scenario

as well as the principle and method of site selection and capacity determination for UPFC

is presented

and a control strategy of UPFC is further proposed. Finally

an example case of Chuxiong power grid in Yunnan Province is given to verify the effectiveness of the above methods and strategies through power flow calculation and transient simulation. It is concluded that the wind power transmission capacity in Chuxiong area can be greatly improved by applying unified power flow controller.
