In industrial power distribution systems, the record of 1.7 failures per year in compensation cabinets continues to trouble equipment managers. Statistics from the State Grid Fault Data Center (report number SGCC-FD2024) show that the direct losses caused by power capacitor explosions in 2023 will reach US$600 million, of which 83% of the accidents are caused by harmonic resonance and life management failure.

Driven by the "Dual Carbon" goals, China's installed capacity of new energy power generation has exceeded 700 million kilowatts, accounting for more than 30% of the country's total installed capacity. With the large-scale integration of intermittent power sources such as photovoltaic and wind power, a new technical challenge has emerged in the power system - excessive capacitive reactive power.

The production environment of petrochemical industries contains a large amount of flammable and explosive gases and dust, which places extremely high demands on the safety of low-voltage reactive power compensation electrical equipment. As a well-known expert in the field of reactive power compensation, Geyue Electric attaches great importance to the upgrading of low-voltage reactive power compensation equipment in extreme petrochemical scenarios.

n this article, Geyue Electric, from the professional perspective of a manufacturer of low-voltage reactive power compensation equipment, will systematically analyze the key influencing factors of electricity consumption in metallurgical enterprises, deeply explore the intrinsic correlation mechanism between reactive power compensation system design and electricity consumption per ton of steel, and propose a comprehensive solution based on dynamic compensation and harmonic control.

n industrial power systems, frequency converters, as highly efficient and energy-saving devices, are widely used in motor control. However, their non-linear characteristics lead to increased grid harmonic pollution, which in turn causes premature failure of traditional capacitor banks. In the following text, Geyue Electric will, from the perspective of a manufacturer of low-voltage reactive power compensation equipment, systematically analyze the deep mechanism of capacitor damage under the load of frequency converters, reveal key failure modes such as harmonic resonance, current overload, and dielectric aging, and propose a comprehensive solution based on harmonic suppression and dynamic compensation, providing equipment selection and operation optimization suggestions for industrial users.

As a key device in the reactive power compensation system, the series reactor relies on the electromagnetic induction characteristics of the inductor coil to achieve all-round management of the power network.
