Research On Electric Load Control System Based On Vxworks Real-Time OS

As a part of the Automatization of Power Distribution, Electric Load Control is also a technique of Electric Load Management. The aim is to involve mostly users in electric power system peak-load by adopting rational electrovalent difference between peak and valley. It uses auto-control technology to promote load ratio, and improve device usage ratio during power generation, supply and user. It is enable to make power network run more economically and safely. And it also provides with great advantages for the whole society.By utilizing the micro-electronics technology,computer technology and control technology, the new-type Electric Load Control System solves the problem that how to measure electric energy accurately and utilize electric energy rationally.Firstly, the paper puts forward the design scheme based on the analysis of market demands and gives an argumentation on feasibility of this scheme. Then it expatiates the circuit design principle of the AC sample system,ARM7 master system and IO interface system, especially explain the application of CAN Bus on the system in detail. Afterwards, the BSP and Driver development of Vxworks Real-Time OS is analyzed. Lastly, it gives a summarization on this system, and brings forward some suggestions.The new-type Electric Load Control System introduced in this paper succeeds in introducing the conception of research and develop environment that is convenient to expand the functions of this system. The system is based on the Advanced RISC Machines CPU and Vxworks Real-Time Operation System. Besides these, the communication part of system adopts the Controller Area Network Bus Technology.The design of this new-type Electric Load Control System has the characteristic of high-stability and multi-function. Therefore, it is extensively applied in the area of Power market and Demand-Side Management.
