Background
Solar farms use semi-conductive components to absorb solar radiation and turn it into electric energy. Solar energy is becoming common in the global energy market because of its endless storage and low cost. Solar energy is developing quickly around the world and is considered an important part of sustainable development in every country. Solar power stations utilize photovoltaic cells combiner boxes, low-voltage DC cabinets, inverter cabinets, low-voltage AC cabinets and step-up transformers.


Project requirements
Photovoltaic power generation monitoring system for photovoltaic power plants in the battery array, bus, inverter, AC and DC power distribution cabinet, solar tracking control system and other equipment for real-time monitoring and control, so as to control the operation of the power plant, to ensure that solar photovoltaic power generation system is completely reliable and stable operation. The field is divided into 15 photovoltaic power generation areas, each area access switch is gathered to the monitoring room. Ethernet switch can be able to adapt to the harsh environment of the scene, the device can work safely and reliably with stable transmission data.


SCADA
SCADA (Supervisory Control and Data Acquisition) system, which is data acquisition and monitoring control system. SCADA system is a computer based DCS and power automation monitoring system; it is widely used in electric power, metallurgy, petroleum, chemical, gas, railway and other fields of data acquisition and monitoring control and process control etc. It can monitor and control the operation of the field, in order to achieve data acquisition, equipment control, measurement, parameter adjustment and various functions of various signal alarm.

Scheme introduction
The solar power plant is divided into 15 zones. Each region 5MW consists of 5 switches, consisting of a single ring, including 4 IES608-2F and 1 IES608-4F. Finally, the IES608-4F of each region is gathered in IES5024-12F to access the monitoring center, which ensures the stability and reliability of the communication.
