This article will introduce in detail the technical deployment and the advantages of the scheme.

Technology deployment

Photovoltaic power station LTE cat 4 modem operation and maintenance remote networking monitoring scheme is mainly composed of the following parts:

Data collection: collect parameters such as power generation, output power, inverter power, ambient temperature, wind speed, and light intensity of the photovoltaic power station through the inverter, combiner box, irradiator, meteorological instrument, and ammeter of the photovoltaic power station, and transmit the collected data to the data transmission terminal through RS232/RS485 and other protocols.

Data transmission: The data transmission terminal transmits the collected data to the network server or the local computer of the management center through 2G/3G/4G and other wireless communication modes to realize remote control and management.

Data analysis: The network server or the local computer of the management center will analyze and process the collected data, generate reports, curves, and other data display forms, and provide data support for the optimal operation of the photovoltaic power station.

Remote control: The network server or the local computer of the management center can realize the remote control and management of the inverter, combiner box, meteorological instrument, and other equipment of the photovoltaic power station through the remote control software, so as to improve the operation and maintenance efficiency and management level.

Advantages of the scheme

Convenient networking transmission: The data transmission terminal supports multiple transmission modes, such as LoRa, LTE cat 4 modems, NB-IoT, etc., which can meet the data transmission requirements in different scenarios.

Industrial LTE cat 4 modem design: the data transmission terminal has industrial characteristics, supports wide temperature and high protection levels, is suitable for outdoor application environments, and is easy to install.

Strong protocol compatibility: The data transmission terminal supports multiple protocols, such as Modbus TCP, and has the advantage of strong protocol compatibility, which can meet different data requirements.

Statistical analysis of data: The network server or the local computer of the management center can conduct statistical analysis on the collected data, generate reports, curves, and other data display forms, and provide data support for the optimal operation of the photovoltaic power station.

Equipment status monitoring: The data transmission terminal can monitor the equipment status of the photovoltaic power station in real-time, such as inverter, temperature sensor, power quality measuring instrument, etc., find faults in time and give an alarm to improve the reliability and stability of the photovoltaic power station.

Remote control and management: The network server or the local computer of the management center can realize the remote control and management of the inverter, combiner box, meteorological instrument, and other equipment of the photovoltaic power station through the remote control software, as to improve the operation and maintenance efficiency and management level.

The LTE cat 4 modem operation and maintenance remote networking monitoring scheme of photovoltaic power station can realize the remote monitoring and management of photovoltaic power station, improve the operation and maintenance efficiency and management level, and provide important technical support for the safe, stable, and efficient operation of photovoltaic power stations.
