Large scale use of Wide Area Measurement System (WAMS) is deployed at many transformer substations worldwide for better power system condition monitoring. In the WAMS architecture, Phasor Data Concentrators (PDCs) receive the datapackages collected by Phasor Measurement Units (PMUs) and send them to the Main Stations for centre computer to analysis. This paper introduces some industrial requirements towards PDCs according to the international standard associations (e. g. IEEE, IEC) and proposes a test for functional and performance requirements (e. g. latency calculation, data aggregation, etc) of PDCs. Catering to special of the distribution network, in the proposed testing process, the capability of the PDCs has been paid more consideration compared to substations. In addition, a software which work as Pseudo-PMUs is designed for the testing in this paper. The proposed software can simulate some error communication (e. g. datapackages lost, data redundancy, etc) for better evaluation. |
