A Novel Method for Onsite Commissioning of Wide-Area Protection

Abstract:

The wide-area protection technology is considered to apply in construction of smart grid, which offers new challenge to verifying work for secondary system. This paper describes a new method for onsite commissioning of wide-area power grid. It can accomplish coordination tests for protection devices in different areas based on numerical simulation and wireless commutation technology. Because structure of power grid is too complex to calculate results of electromagnetic transient efficiently. A new approach of simulation is shown in the paper, which uses FDNE circuit to replace external system. And an example of test is offered. The simulation result indicates that electromagnetic transient computation with FDNE can be satisfied with debug work for occurrence chains in smart grid.
