Application of IEC 61850 to the communication of a large-scale photovoltaic power generation operation - Web service and conformance test -

Abstract

We developed a SCADA server as a prototype to evaluate the applicability of IEC 61850 for the operation of largescale photovoltaic (PV) generation systems. IEC 61850 and Webservice technology (IEC 61400-25-4) are applied to the data model and the server communication protocol. We also developed a test client for the conformance test, which was then executed. The result showed that the server conformed to IEC 61850 on the data model and protocol. Therefore, the applicability of IEC 61850 to the operation of a large-scale photovoltaic (PV) generation system is confirmed.
