The frequency monitoring network (FNET) provides a low-cost, easily deployable method for wide-area monitoring. FNET has the capability to realize long term, high density and continuous monitoring of large interconnected power systems. In effect, there are potentials for ground-breaking research on wide-area monitoring and control. In this paper, low frequency oscillations in the Eastern Interconnection...
This paper investigates Chinese standards for power system security and the practices in the relevant strategy. Considering the cascading features of typical system-wide blackouts around the world, further emphasis is given to integration of various wide area measurements, trajectory-based knowledge extracting, on-line quantitative security analysis, and adaptive optimization of preventive control,...
In this paper, key techniques, limits and feasible applications of wide area measurement system (WAMS) and wide area control system (WACS) are investigated and the framework for Wide area Monitoring Analysis Protection-control (WARMAP) is introduced to break those limitations. Based on engineering experiences in China, application functions depending merely on phasor measurement unit (PMU) data are...
With investigation on recent blackouts around the world, the three-defence-lines criterion, which has been the security standard for power systems in China, is reviewed. An adaptive space-time cooperative framework, named as Wide ARea Monitoring Analysis Protection-control (WARMAP) for defending power system against blackouts is introduced in this paper. It upgrades the individual defence lines to...
