Project Name: SPIC 500MW PV Power Generation Affordable Internet Access Demonstration Project
Model and Quantity: MIEN6208 (937 units)
City: Chaoyang City, Liaoning Province, China.
SPIC Chaoyang 500MW project is located in the mountainous area in the southwestern part of Chaoyang City, Liaoning Province. All power generation arrays on site are on the mountain. Chaoyang City has ample daylight and ideal photovoltaic power generation effect. It is the country's largest batch of parity grid demonstration projects. The project is divided into 6 bidding sections, which are completed by different inverter manufacturers. It is a big challenge for the cooperation of various manufacturers of switch communication.
The site is divided into two regions, the north and the south. Each region has 10 power collection lines. Each power collection line has a different number of square arrays. At most one power collection line has 24 square arrays. The site is powered by three inverters suppliers, SUNGROW POWER, HOPEWIND and SI-NENG. The inverter communication is completed by MAIWE and one other brand. The field ring network protocol adopts the RSTP protocol group ring network. Due to the large number of field switches and the cooperation of the two manufacturers, our company send senior technicians to the site to coordinate with the debugging. With the strong cooperation of the owner and other brand manufacturers, all 20 ring networks work normally, and the project was successfully connected to the grid as scheduled.
