Description

Technical Field

[0001] The invention relates to the technical field of light intensity prediction, and in particular to a capacitor detection method for reactive power compensation equipment. Background Art

[0002] Reactive power compensation equipment plays a role in improving the power factor of the power grid in the power supply system, reducing the loss of power supply transformers and transmission lines, improving power supply efficiency, and improving the power supply environment. Therefore, reactive power compensation devices are in an indispensable and very important position in the power supply system. Reasonable selection of compensation devices can minimize the loss of the power grid and improve the quality of the power grid. In order to improve the power quality of the power supply of the power grid, one of the commonly used methods is to use parallel capacitors to compensate for inductive reactive power, so as to improve the system voltage and power factor and reduce line losses.

[0003] The safety inspection of capacitors of reactive compensation equipment is a very important task in the operation and management of traditional power distribution facilities. Usually, the safety inspection of capacitors relies on uninterrupted manual work, which can timely detect the bulging and leakage of capacitors and organize replacement as soon as possible. However, it is difficult for manual work to monitor continuously for 24 hours, and there are often "fish that slip through the net". As a result, the phenomenon of capacitor fires inducing fires in distribution rooms often occurs. When a capacitor fails, it generally follows the process of internal impedance deviation → single group failure → heating bulge → electrolyte precipitation → heating, fire or combustion. With the increase of nonlinear devices such as inverters and LED lighting systems in power loads, the power quality has deteriorated significantly compared with before, and the frequency of capacitor failures has increased year by year.

[0004] However, the existing reactive power compensation equipment cannot accurately determine whether the capacitor in the reactive power compensation equipment needs to be repaired or replaced, and thus the reactive power compensation equipment cannot play a role in improving the efficiency of power grid energy utilization.
