The invention relates to a distributed photovoltaic distribution network monitoring system and a control method thereof, which solves the defect that the photovoltaic distribution network system cannot be effectively supervised compared with the prior art. The invention includes a background control terminal, a main power distribution line and several power distribution lines, several power distribution lines are connected to the main power distribution line, and photovoltaic modules are connected to the power distribution line and connected to the main power distribution line through the power distribution line Lines, low-voltage JP cabinets are installed on the main distribution line, current transformers are installed in the low-voltage JP cabinets, current transformers are installed on the main distribution lines, and island monitoring devices and several photovoltaic monitoring devices are also included. The monitoring device is installed on the main distribution line, and the photovoltaic monitoring device is installed on the distribution line. The invention establishes a photovoltaic area monitoring system, centrally manages each photovoltaic power generation device scattered on the distribution network line, and completes the unified control of the distributed photovoltaic of the distribution network line.
Description
technical field [0001] The invention relates to the technical field of photovoltaic distribution network, in particular to a distributed photovoltaic distribution network monitoring system and a control method thereof. Background technique [0002] Photovoltaic technology has been widely used in daily life. In rural areas in mountainous areas, photovoltaic panels have been widely installed and used in rural households. On the parallel connection between a large number of farmer distribution lines and the main distribution line, the main distribution line is prone to an island effect, and the distribution line of the farmer is also prone to a no-voltage state of the distribution line due to the lack of power from the photovoltaic panels. However, the amount of action and electrical quantity of the original switch of the user's photovoltaic system cannot be effectively monitored in real time in the power system, which brings huge safety hazards to the operation of the power gr...
