VOLTAGE IS NEVER PERFECT 60% OF POWER QUALITY COSTS ARE CONSEQUENCE OF VOLTAGE SAGS Modern industry is becoming more automated and the sensitivity of processes to Power Quality events is increasing. It is generally recognized that quality is an important aspect of the electricity service. Not only low prices are important, also high-quality matters to customers. Price and quality are often complementary aspects; together they define the value that customers derive from consuming electricity. In practice the voltage is never perfect. If the quality of electricity supplied to the plants drops below...

WHAT ARE VOLTAGE SAGS? A voltage SAG is a temporary reduction of the Voltage RMS below a specific threshold at an electrical supply line point. SAG STARTS WHEN VOLTAGE GOES LOWER THAN 90% OF NOMINAL VALUE AND ENDS WHEN VOLTAGE RESUME ABOVE THIS VALUE NOMINAL VOLTAGE RESIDUAL VOLTAGE Generally voltage SAG happens when the residual voltage decreases between 10 and 90 percent of nominal voltage for one-half cycle to one minute. Voltage SAG duration is considered within 10ms up to 1min. The great deal of Voltage SAG have a duration lower than 1 second and a residual voltage higher than 40% of the...

WHERE DO THE VOLTAGE SAGS COME FROM? MOST VOLTAGE SAGS LAST LESS THAN ONE SECOND AND HAVE A RESIDUAL VOLTAGE EXCEEDING 40% • The voltage SAG propagates from the higher voltage levels to the lower ones, the load is often connected to a voltage level lower than the point of failure. • Faults in the network cause deep voltage SAGs if they occur near loads. • According to an Italian CESI study, the incidence of voltage SAGs is much greater in the case of an aerial MV network than with underground cables. RELEVANCE OF VOLTAGE SAGS VOLTAGE SAG COST IS NORMALLY LOWER THAN A VOLTAGE SUPPLY INTERRUPTION...

Oxygen, thanks to a suitable sizing of the power components and a remarkable response speed (<3 milliseconds) is able to face lowering (SAG) of the grid voltage of a maximum duration of one minute. The energy required is taken directly from the network. Current models are able to cover network downing up to 50% of the nominal value (-50%). The voltage compensation on the buck/boost primary winding is performed by IGBT static switches controlled by a microcontroller. The microcontroller system monitors the output voltage and determines the opening or closing of the IGBT contacts ensuring the best...
