Problems solved by technology

The analysis of the technical characteristics of the high-pressure sodium lamp, one of the gas discharge lamps, in the above-mentioned literature is obviously partial. It only considers the negative slope of the volt-ampere characteristic curve of the high-pressure sodium lamp in the discharge state, and does not consider its power characteristics, let alone its accompanying township. Such "power saving" method is a purely commercial power saving at the expense of the effective lighting and normal service life of gas discharge lamps. It lacks theoretical basis and is unscientific.

Embodiment

[0066] Embodiment proves that the present invention has the following beneficial effects:

[0067] ①Because the street lights enter the power supply valley section from 10 o'clock at night, the voltage is 10-20% higher than the power supply level section. If the street lights are not implemented with energy-saving intelligent control, under normal circumstances, the street lights are higher than the design power of the lights 10-20% working condition, therefore, the actual power-saving effect after implementing the technology of the present invention can reach 20-45%;

[0068] ②In the case of implementing intelligent power saving, the flux of high-pressure sodium lamps should not be lower than 90%;

[0069] ③It can automatically, scientifically and reasonably turn on / off street lights according to the natural light intensity, save power consumption of the power grid, and ensure driving safety at night;

[0070] ④Ensure the safe use of gas discharge lamps in hot start state; ...

Abstract

The invention provides an intelligent electricity saving optimal control method, belonging to the energy saving technology field. The invention determines gas discharge road lamp input voltage, that is AC output voltage target value, through a gas discharge lamp safety control four side graph made up of a gas discharge lamp lowest lamp voltage-power characteristic curve, a gas discharge lamp highest lamp voltage-power characteristic curve, a gas discharge lamp highest lime power curve and a gas discharge lamp lowest limit power curve, a ballast characteristic curve and the selected electricity saving level to keep the gas discharge road lamp in optimal control state through the whole course. The method in the invention can turn on / off road lamp according to the natural illumination automatically, saves the electricity in 20-45% while insuring driving safety at night.

Description

technical field [0001] The invention relates to an automatic control method in the technical field of energy saving, in particular to an intelligent power saving optimal control method. Background technique [0002] As we all know, the energy and resources of the earth are limited. In order to ensure the sustainable growth of the economy to the greatest extent, people must not relax the conservation of existing energy while actively looking for new energy and developing renewable energy. Issues of common concern and consensus. In order to save and utilize energy efficiently and to the greatest extent, the most fundamental way lies in the application of advanced science and technology. Among them, how to make gas discharge lamps effectively use and save energy is a very prominent and urgent technical task at present, because the superior luminous flux characteristics of gas discharge lamps are used as street lights, and their large number has spread all over urban and rural ...
