摘要

It is urgent for modern society to save energy and protect environment. But the efficiency of traditional lighting equipment which occupies a rather high proportion of total electric load is very low. Now, they are more and more instead by power electronics based devices, such as energy-saving lamps or LED lamps. For the different characteristics from that of traditional devices, the new kind of lighting equipment may have uncertain influence to power grid. Firstly, their topologies and control schemes are studied and analyzed. Then, the general models, which are suitable for simulation analysis, are proposed. After that, the simulation study and physical experiment are carried on respectively. It is revealed and manifested that the characteristics of both energy-saving lamp and LED lamp are quite different from that of traditional lamps, and may have adverse impact on the safety and stability of power grid.
