Влияние подключения фотоэлектрической станции мощностью 2 МВт на устойчивость энергосистемы в Ираке-Сулеймания
Аннотация
Подключение фотоэлектрических систем повышает энергоэффективность электрических сетей за счет снижения потерь электроэнергии и улучшения профиля сетевого напряжения. При этом нежелательными последствиями являются колебания мощности и напряжения, сбои в работе защитных устройств, недостаточная нагрузка и перегрузка фидеров, а также гармонические искажения. На динамическую нестабильность напряжения сильно влияют параметры фотоэлектрической системы, обусловленные эффектами рассеивания облаков, температурой и быстрым изменением солнечной радиации. Статья посвящена исследованию влияния модели фотоэлектрической генерации мощностью 2000 кВт, подключенной к сети, на устойчивость энергосистемы, в частности на стабильность напряжения и частоты. На первом этапе определены полная характеристика и конструкция фотоэлектрической установки мощностью 2000 кВт. Кроме того, также будет изучен соответствующий контроль и соответствующая рабочая реакция. Эта модель и ее взаимодействие с частотой и напряжением энергосистемы будут проанализированы с помощью моделирования в Matlab. Применяя системную модель, во всех нештатных ситуациях, таких как нарушение напряжения сети в точке общего присоединения и в напряжении источника сети, потери сетевой системы, неисправность, изменение частоты, нагрузки и освещенности, будут исследованы и задокументированы. Приведены результаты моделирования.
