Design of networked monitoring system of PV grid-connected power plant

摘要

Requirement of PV station and differences between modern and traditional monitoring systems are analyzed. Based on embedded PV grid-connected controller and Ethernet technology, monitoring system of PV Grid-Connected Power Plant is designed roundly. Definite design of the hardware and software are achieved with the Principle of hardware selection and communication protocols standardization of PV grid-connected controller. With less cubage and lower cost, the system runs well, which has great significance on current projects.
