Analysis of Abnormal Operation of Heavy Overload Control Device Based on Battery Energy Storage

With the increasing economic and living standards of residents, the use of electrical equipment is also more frequent. Especially in special periods or weather conditions, the load power of the distribution network will increase exponentially, even exceeding the rated power of the distribution transformer. Applying power electronic compensation devices with battery energy storage system is an effective solution for heavy overload control. Thus, the reliability of heavy overload control devices is critical in improving the power distribution quality. This paper takes a heavy overload control equipment in Kunming as the research object, analyzes the reasons for its abnormal operation in detail, and puts forward suggestions for improvement, which is of great significance to the safe and stable operation of the power distribution system in this area.
