The professional and efficient operation team provides a 7*24 uninterrupted production safety guarantee and provides output-guarantee operation services covering the entire life cycle of the PV power plant.

The O&M power stations cover over 40 cities across China, mainly in the central and eastern regions, and have formed a demonstration effect to radiate the western part.

Tongwei is currently operating more than 50 power stations, mainly "Fishery&PV Integration," as well as a few mountainous, ground, and distributed power stations.

Capacity The total capacity of O&M power stations exceeds 2.5GW, including several 100MW-level projects.

Tongwei creatively initiates the "Fishery&PV Integration and intelligence plus" operation mode and provides high-quality O&M services. As of June 1, 2021, the safe production days of power stations reached 1980.

According to the requirements of the Regulation for the Inspection and Repair of Photovoltaic Power Station and the Regulation for the Inspection and Repair of Substation, the professional electrical test team regularly conducts a special comprehensive inspection, cleaning, testing, measurement, and regular replacement of components for electrical equipment to eliminate equipment and system defects and ensure that the overall function of the equipment meets the requirements.

The "Fishery&PV Integration" IOT Electric Test team began the maintenance, testing, technical transformation, and emergency repair of substations, power stations, and distribution stations in the power industry in 2019. The team insisted on conducting electrical tests at night to avoid power outages. In 2019, the night maintenance and test exceeded 80 days; in 2020, the number was 70 days. There was no 1kWn planned power outage loss. The work quality, ability, and sense of responsibility of the electrical test team have been affirmed by many parties.

"Water, land and air" omni-directional intelligent unmanned inspection equipment
The unmanned inspection equipment such as unmanned aircraft, unmanned boats, and unmanned vehicles equipped with thermal IR imaging cameras and visible light imaging cameras work together with independently developed professional post-processing software to automatically detect module dust, dirt, cracks, shading, heating, and other abnormal conditions, scan points in the decision areas and intelligently identify various anomalies shading hot spots, modules heating conditions, module zero current, module diode bypass, etc. Help improve the efficiency of power station fault elimination, fully tap the value of power stations, and increase the power generation of power stations.

Intelligent PV centralized O&M system
The intelligent PV centralized O&M system integrates the Internet mindset to carry out PV power station O&M management, focusing on the unified management of the entire production process, equipment assets, data assets, and the entire life cycle. It realizes a panoramic VR monitoring of the power station, monitors equipment operation data and status, automatically positions faulty equipment and prediction and warning, intelligently analyzes power station daily operation data, compares various electricity data, quantifies power station operation quantitative assessment indicators and other production indicators, and realize information management, power station personnel management, equipment maintenance process management, equipment O&M process management, safety production management, power station assessment management, financial settlement management, etc. during the whole life cycle of power station production.
