Regularly check whether the connection between the controller and the frequency converter and other equipment is firm, and check whether the grounding connection between the controller and the frequency converter is firm and tight as needed; Check whether the components on the circuit board in the controller and inverter are soldered or damaged, and repair or replace them by welding as needed.
lightning protection device
It is rainy and thunderous in summer. Regularly measure whether the grounding resistance value of grounding device meets the design requirements; Regularly check whether all equipment parts are reliably connected to the grounding system. If the connection is unreliable, it must be welded firmly. After a thunderstorm or before the rainy season, check whether the lightning protection devices and equipment installed in the square junction box are invalid and replace them in time as needed.
Regular training of personnel
The training was initially aimed at professional and technical personnel. In view of the key and difficult problems in operation and maintenance management, professional and technical personnel are organized to carry out various internal special trainings, and technicians are sent to carry out systematic relevant knowledge training to improve their professional skills.
It is also important to train power plant operators, who are usually selected locally. Due to the low education level of local personnel, the training work starts with the most basic electrician knowledge, and carries out theoretical knowledge training, special operation training, practical operation training and power plant operation regulations.
After training, they can understand and master the basic working principle of photovoltaic power generation system and the functions of various devices, and realize the daily maintenance of the power station as required, and have the ability to judge the causes of common faults and solve them.
Establish unobstructed information channels
Designate a special person to be responsible for the contact with power station operators and equipment manufacturers. When the power station breaks down, the operators can submit the problem to the relevant departments in time, and at the same time, they can inform the equipment manufacturers and maintenance personnel to go to the site for maintenance in the shortest time.
