Analysis on Voltage and Reactive Power in Civil Lighting

Street lamp has become the essential functional unit in society for its widely use , Street lamp power energy saving has become a very worth studying problem high demand. Aiming at such a demand, this paper proposed a kind of optimizational energy saving streetlight that based on the voltage and reactive power, this article put forward such a research mainly aims at the demand of Jinan street lamp management. The research improved the grid power factor, reduced the network pressure drop and reduces the energy consumption of street lamp. It upload the master station through GPRS network real-timely, And accept command such as mode conversion, parameter setting, time checking and capacitor switching. It implements the voltage optimization function, remote monitoring and control functions on the basis of ensuring road illumination and uniformity, Which realized street light energy-saving and reduced the loss of lines and transformers at the same time. And it protect lighting lamps effectively. Examples show that the study further improved the management level of Jinan street lamp, it realized the double harvest of electricity environment optimization and electrical energy saving, Which made a great contribution to energy-saving society construction.
