Functional Test for Phasor Data Concentrator in Distribution Network

Abstract

With the large amount of distributed energy connected to the power grid, the control and protection of the traditional distribution network is becoming more and more difficult. The synchronous phasor measurement unit (PMU) can realize the monitoring of the power grid well, but it is mainly used for transmission network and the cost is high. In recent years, the cost reduction of PMU and the maturity of technology have enabled set up a large number of PMUs in distribution networks, and the formation of Wide Area Measurement Systems (WAMS) has become possible. In order to study the function and performance of phasor data concentrator (PDC) in distribution network, this paper establishes PMU, PDC and main station test platform, and combines the existing standards to test PDC. In view of the deficiencies, combined with foreign relevant standards, the test methods and evaluation criteria are proposed for the data latency and convergence of the distribution network PDC.
