The Design And Implementation Of Fault Analysis Of The Smart Meter Data Acquisition

In recent years, with the social and economic development, increasing social demand for electricity, the power supply has become tighter. Moreover, since a large number of applications of nonlinear loads, resulting in producing large amounts of high-order harmonic in the power system, which causes great harm to the power system. In this case, it needs the power parameter harmonic situation to be detected in real time and accurately.As is known to all, in industry and daily life, electricity is closely related to social and individual and the significance, because of the high current and voltage is too low, can affect the normal use of all kinds of electrical equipment efficiency and equipment life and the voltage, current, active power, reactive power, power factor and frequency electrical parameter of the accurate and rapid detection. And then take effective measures to ensure that equipment in good running. From research shows, on the development of a kind of multi-functional electric power parameter detection device has very important significance.This system is based on the core of CS5460 chip and SCM STC89C52, with the clock module, display module, keyboard control module, memory module and the C language software design. The CS5460 can be used to measure the instantaneous voltage and instantaneous current and instantaneous power.These measurements are 24 symbols and full scale unsigned data format as a output. Micro-controller read and write data through its connected via SDI and SDO and display on the LCD screen.Towns and the rural electric reform gradually thorough, all kinds of measuring tools appear constantly in the market. A variety of measurement tools used in the measurement method is different also. Using simple single phase meters CS5460 chip design can be used in industrial field of electricity data acquisition and simple power calculation, the use of CS5460 design of digital meter is suitable for residential electricity metering meter scheme of the most accurate and cost-effective opened the new field of electric meter design, is the next generation civil electric meter of the ideal products and the best industrial solutions.This device can be used to measure current, voltage, active power, reactive power, apparent power, power factor and harmonic analysis, and its computing is fast, reliable, and scalable.On the basis of this, joined the initiative to report the type of electric energy data acquisition terminal(hereinafter referred to as collector) collector is for domestic all kinds of decentralized grid industry operations required to develop a new generation of electric energy acquisition equipment, can satisfy the various users to upload data, access the main different specifications meter, automatic timing report data remote transmission, and the demand for high power acquisition requirements and design.
