Wide Area Dynamic Measuring System of Northeast Power Grid

TLDR: In this article, a wide area measurement system (WAMS) is built in Northeast Power Grid in China, in which the architecture containing analysis master station and phasor measurement (PMU) systems is adopted to catch dynamic processes and behavior features of power grid being disturbed.

Abstract: Along with the continual enlargement of power grid interconnection scale in China, the impact of load model on calculation results of system simulation cannot be neglected. To choose appropriate load model for simulation, according to the principles of accuracy, reliability, security and practicability and by means of integrating up-to-date technologies of phasor measurement, communication and computer, a wide area measurement system (WAMS) is built in Northeast Power Grid in China, in which the architecture containing analysis master station and phasor measurement (PMU) systems is adopted to catch dynamic processes and behavior features of power grid being disturbed. A powerful analysis master station of the WAMS is equipped in dispatching center of Northeast Power Grid, and different kinds of PMU devices provided by three manufacturers are equipped in twelve power plants and substations. The presented WAMS are tested by manifold ways in long period and by which a lot of dynamic processes of actual power grid are recorded, the recorded processes can offer the data for the check of simulation analysis, but also provide a brand-new dynamic monitoring measure for secure and stable operation of power grid.
