With the wide application of photovoltaic system, the harmonic problem caused by it is also increasingly concerned. Harmonics will not only affect the operating efficiency of the photovoltaic system itself, but also have a negative impact on the power quality of the grid, resulting in equipment over
In today's era of industrialization and commercial development, power quality has become a key factor restricting enterprise efficiency and equipment life. In the industrial production process, all kinds of nonlinear loads are flooded, and the complex and changeable electrical equipment in the comme
In modern life, the importance of electricity is self-evident, large to the operation of large equipment in factories, small to the use of household appliances, are inseparable from power support. However, have you ever noticed that sometimes electrical appliances will malfunction inexplicably, and
