Dynamic telemetry network for remote Photovoltaïc Stations

Our aim is to develop a process to measure and supervise parameters of remote photovoltaic stations, in order to transmit it via radio to the operator. The management of data coming from different parts is operated by PLC (Programmable Logic Controller). PLC uses MODBUS: it’s a simple and robust serial protocol with master/slave hierarchy (RS485) deployed on a serial link, asynchronous, differential (up to 10 Megabits/s). Every PV station will contain necessary sensors and detectors to supervise electric and solar parameters in order to give elementary digital flows. These flows will be directed to make terminal stream by using appropriate multiplexing step by step. After, this transport stream TS will be broadcasted using specific support which constitutes our new idea proposed in this book: Indeed, we propose to make process based on the TS and put it over 57 KHz subscriber available in FM multiplex spectrum as it was detailed in the papers.
