Existing Reconstruction Design under the “Double Carbon” Target Strategy——Power Quality Improvement and Protection Electrical Equipment Setting
Abstract: In this paper, combustion accidents caused by power quality problems and power failure caused by non-selective action of protection appliances in practical engineering are analyzed. Combined with field measurement and theoretical calculation, an effective solution is put forward, and the application prospect of regional selective interlocking protection appliances is proposed. It also puts forward a new idea of electrical design under the "double carbon" goal strategy.
Keywords: power quality; harmonic current; ground fault protection; zone selective interlock protection;
