PV Power Generation Information Modeling Based on IEC61850

In recent years, photovoltaic (PV) power generation is developing rapidly on account of its environment friendliness. However, the PV devices between different manufacturers could hardly interoperate because of different model and protocols they applied. This paper built the information model for PV power generation based on IEC61850, which is more normative and convenient for PV plant configuring. The method abstract functions of PV devices to Logic Nodes (LN), and assembling related LNs into Intelligent Electronic Device (IED). This object-oriented model is strong in commonality and practicability, and is beneficial for devices interoperating. The model in this paper is suitable, and has been applied in practical PV project in Qinghai province, China.
