Allowing for harmonics
Depending on the magnitude of harmonics in the network, different configurations should be adopted.
• Standard capacitors: when no significant non-linear loads are present.
• Oversized capacitors: when a few non-linear loads are present. The rated current of capacitors must be increased in order to cope with the circulation of harmonic currents.
• Harmonic rated capacitors used with detuned reactors. Applicable when a significant number of non-linear loads are present. Reactors are necessary in order to limit the circulation of harmonic currents and avoid resonance.
• Tuned filters: when non-linear loads are predominant, requesting harmonic mitigation. A special design is generally necessary, based on on-site measurements and computer simulations of the network.
[Schneider Electric]Учет воздействия гармоник
В зависимости от амплитуд гармоник, присутствующих в сети, применяют разные устройства компенсации реактивной мощности:
● Стандартные конденсаторы: при отсутствии значительных нелинейных нагрузок.
● Конденсаторы с увеличенной реактивной мощностью: при незначительных нелинейных нагрузках. Необходимость применения конденсаторов с увеличенным номинальным током объясняется тем, что они должны выдерживать циркуляцию токов гармоник.
● Конденсаторы с увеличенной реактивной мощностью и с антирезонансными дросселями применяют при наличии значительных нелинейных нагрузок. Дроссели необходимы для подавления циркуляции токов гармоник и предотвращения резонанса.
● Фильтры высших гармоник: в сетях с преобладанием нелинейных нагрузок, где требуется подавление гармоник. Обычно фильтры конструируют для конкретной электроустановки по результатам измерений на месте и изучения компьютерной модели электросети.
