This paper proposes a non-contact current measurement method for three-phase rectangular busbars based on TMR (tunneling magneto-resistance) sensors, due to their advantages of large dynamic range, wide bandwidth, light weight, and easy installation. A sensor composed only three sensors is developed the are respectively placed at location with certain distance from surface each busbar measure magnetic fields generated by currents. To calibrate sensor, i.e., establish relationship between...
At present, the power grid is still in an inflexible state form of massive information representation, lack effective visualization means to efficiently display calculation results various applications. To provide better service for system monitoring operation, this paper introduces design and implementation a general open data mining platform. level mining, function module adopts J2EE enterprise component analyze combine rough set neural network algorithms, preprocess original data. In...
In this paper, a non-contact measurement method of the power line voltage based on capacitive coupling principle is proposed, which realizes reliable waveform. Firstly, basic introduced in mainly includes self-calibration and online sensor. The high frequency signal injected into network sensor to implement ratio. Then, digital integration used integrate output achieve Secondly, prototype corresponding processing circuit are designed. Finally, test platform built, 220V/50Hz waveform carried...
In power system, reliability and economy are always mutually contradictory. Considering that to get a higher supply we should invest reform the grid, cost-benefit analysis is necessary select best solution in number of different construction programs order level with reasonable investment. This article studies method its application optimization distribution network programs, illustrates feasibility through numerical examples.
