| Abstract: |
| The real-time transient stability detection and emergency control technology based on wide area response has
become a hot research area in power system stability studies. Several different technologies have been proposed,
but lots of problems remain to be solved before they can be applied in practice. A wide area measurement system
(WAMS) based test platform is developed for transient stability detection and control. The design as well as main
function modules of the platform are introduced. In addition, three generator power angle prediction methods and
six response based transient instability detection technologies are given. Results of engineering application
demonstrate that the developed test platform can provide a real-time operation environment, which can effectively
compare and analyze the validity and practicability of these transient stability detection technologies. Based on the
measured perturbed trajectories from actual power systems or the Real-Time Digital Simulators (RTDS), the platform
can realize the assessment and visual result presentation of various responses from different transient instability
detection technologies. The test platform can be applied to different power systems and it is convenient to embed
new transient instability detection modules. Meanwhile some deficiencies and shortcomings in engineering
application are pointed out and corresponding suggestions are given. In conclusion, the hardware and software
structure, function modulus and engineering applications are presented. The application in actual power systems
shows that it has a good application perspective. |
