Увод

A power conditioner supplies the power (outputs the current) to the grid by using the voltage difference between grid voltage and output voltage. Такође, it constantly monitors the grid voltage and frequency so that it can adjust the output voltage and frequency as required.

Проблем

  • Inverter controlled equipment stops because it detects a fault on the commercial power supply
  • Malfunction of peripheral equipment
  • Power cannot be sold back to the utility company due to voltage fluctuation of the commercial power supply (especially when the voltage increases). Due to fluctuation of neighboring load conditions, the voltage of the commercial power supply fluctuates, causing the safety system of the power conditioner to prevent the selling of the power.

Анализа

Следеће ставке треба да се мери истовремено:

  • Флуктуација Напон
  • Флуктуација фреквенција – Model PW3198 can measure the 10s average frequency required for Class A classification of the IEC61000-4-30 standard. Додатно, the PQA can measure the average frequency of 200ms aggregation and 1 cycle frequency. By using these additional capabilities, it helps to confirm the stability of the output frequency from a power conditioner.
  • Пролазни пренапона, Таласни облик изобличења – This is often generated by lightning strikes, switching from generation to consumption, grid switching, итд. It causes malfunction in equipment and solar power generation system, итд.
  • Ударна струја
  • Секундарне фреквенције (Both voltage and current)
  • Високи реда хармоници
  • Треперење

Такође, power and integrated power (consumption, re-generation) can be measured simultaneously with the power quality parameters.
