Considering future smart distribution grid (SDG), the protection and control technology of traditional distribution networks is facing new opportunities and challenges. This paper proposes a Multi-Agent System (MAS) based protection and control method for smart distribution grid. The MAS is consist of intelligent distributed terminal (IDT), control master and communication network. Each IDT is regarded...
Due to the distributed capacitance, the conventional current differential protection has unsatisfying performance. Considering matrix pencil algorithm can accurately analyze the composition of fault transient currents, a novel pilot protection principle using only current data is proposed in this paper to solve the above problem. This principle adopts model recognition concept. Firstly, the theoretical...
Real-time Dynamics Monitoring System(RDMS) is applicable to monitor the dynamic behaviors of large region grid, such as low-frequency oscillation, short-circuit, frequency fluctuation, etc. For the perturbation in power systems occurs incidentally, it's difficult to collect enough cases for an complete test on RDMS, which may lead to potential risks of outage. So it's necessary to study more efficient...
Fault Processing is the most important part of dispatchers routine monitoring work, which is significant to improving processing efficiency, shorten the processing time and prevent further deterioration of the accident when enhance its intelligent level. From the features of dispatchers fault processing, this paper presents a general framework of large grid online decision-making support for accident...
