By analyzing the LCD controller NT7520 and rabbit core RCM3110,we give the interface circuit and partial program of using RCM3110 to connect with LCD controller NT7520.It has been used in intelligent electricity management terminal successfully.
The centralized electricity control system is developed against the problems existing in the traditional electricity management and offers a technological platform for the modernization of electricity management.
This paper briefly introduces the harmfulness for enterprises caused by electricity wastage and the actual significance of wastage reducing and energy saving measures on enterprises, and from the aspects of the technical application and electricity management, expounds some main measures of wastage reducing and energy saving.
Presents common problems with rural power supply in Harbin area identified through general inspection of rural power supply and suggests ways and means to promote reforms of rural power supply network and management system to achieve unified pricing for urban and rural power supplies through unified network thereby standardizing rural power supply management in Harbin area.
On the basis of the practice of power supply management,with the essential conception of traction power loss,the paper analyzed the main factor of power loss,put forward technical management methods,and proposed to improve the management of power loss with new conception and methods to raise the economic efficiency of the whole branch.
The paper evaluates the affection of `One family,One ammeter' reconstruction,and analyses its utility management problem,and the paper puts forward some suggestion about improvement service combining to the practical conditions of Qinghai province.
The calculation means can promote clients increasing load efficiency then improve generation device utility efficiency and relieve the pressure of tense provide and requirement contradiction and enhance power utility management level.
The severe power supply situation in Fujian during the summer period in 2005 is predicted. Analyzing the characteristics of local economy, grid load, and power consumption of customers in Fujian, the 6-level preplan for orderly power utilization based on “three principles” and “three factors” adopted by the company is introduced. The orderly power utilization management mechanism innovated, and the 10 measurements for orderly power supply are described in detail.
This paper introduces the performances,the principles and the field-tests of theradio-controlled load device.Facts have proved,after two years operation,that theradio-controlled load device is reliable and effective.By this technical means fordirect load control and management is successful.
The weighted average power factor now adopted in the manipulation of power supply is disadvantageous.In this paper,two equivalent power factors of a varying load in operation are deduced from the principle that the volta- ge loss is equivalent to the energy loss,and a preliminary measuring process is suggested
The condition of electricity consumption in steel rolling production in China is discussed inthis paper. It is pointed that the potential of electricity saving in rolling mills is very big. The possibility and measures for electricity saving in rolling mills are stated in detail. Theyare mainly: increasing efficiency; improving rolling technology; innovating old rolling mills thatconsume more energy; perfecting electricity management and widely utilizing new technology forelectricity saving.
