At 12:45 on August 4, 2022, a dispatching center received a report from a 100 MW photovoltaic power generation base. It was reported that the incoming line switchgear on the 35 kV low - voltage side of the main transformer at the collection station was on fire, and the protection action tripped. After receiving the notification, relevant personnel went to the site and carried out on - site accident investigation together with the operation technicians. Through on - site inspection, it was found

1 Significance of Selecting and Optimally Designing Wind Turbine Transformers in Wind FarmsAs wind power systems spread, more power transformers are integrated, boosting total equipment capacity and operating losses. Transformers, made mainly from costly silicon steel sheets, copper windings, and foils, are also tough to design. Thus, optimal design and scientific selection are needed to meet technical, national - standard, and user requirements.To ensure stable transformer operation, study thei

1. Brief Introduction to the Photovoltaic Power Generation ProcessThe operation process of photovoltaic power generation is as follows: First, individual solar panels are connected in series to form photovoltaic modules, and the modules are arranged in parallel through combiner boxes to form a photovoltaic array. Solar energy is converted into direct current (DC) by the photovoltaic array, and then converted into three-phase alternating current (AC) through a three-phase inverter (DC - AC). Subs
