提出一种适用于高压并网的风电场调度配合型无功运行接口,即 IVOCD.IVOCD 根据电网的具体特点将电网电压调度要求转换为接口的运行参数,同时检测电网电压,使风电场无功输出处于一个特定运行区域内,以适应不同电网电压的运行需求.以广东湛江电网为例,证明了 IVOCD 能够在电压较低时提供无功支撑,在电压较高时吸收多余无功,从而进行主动调压,使电压运行更加安全,具有很好的适应性和实用性.
提齣一種適用于高壓併網的風電場調度配閤型無功運行接口,即 IVOCD.IVOCD 根據電網的具體特點將電網電壓調度要求轉換為接口的運行參數,同時檢測電網電壓,使風電場無功輸齣處于一箇特定運行區域內,以適應不同電網電壓的運行需求.以廣東湛江電網為例,證明瞭 IVOCD 能夠在電壓較低時提供無功支撐,在電壓較高時吸收多餘無功,從而進行主動調壓,使電壓運行更加安全,具有很好的適應性和實用性.

A new wind farm interface of var operation coordinated with dispatch (IVOCD) for high voltage grid is proposed. The parameters of the IVOCD can be changed for specific grid and voltage dispatch requirement, and it puts voltage area constraint on var output of wind farm to meet various operation situations. Take Zhanjiang grid as case and the case shows that the IVOCD is very adaptive and practical for high voltage grid, since IVOCD provides var support when voltage is low, while absorbs var when voltage is high, making voltage safer.
