Simulation Research in Neuron Network Status Selector in Direct Torque Control
ZHANG Su-bing, WANG Cong
1998, 24(3): 29-31.
Abstract:
Neuron network now has been paid more attention in industrial application, but its application in remote control is still scare to see. Here the methods of selecting inverter on off status by neuron network in DTC system are discussed, together with simulation methods and stages.
Application of Optic Fiber Sensing Technique in Coal Mine Electric Parameters Measuring
CHEN Rong-guang, WANG Cong-xiao
1998, 24(3): 32-34.
Abstract:
The paper introduces the application of optic fibre voltage,current sensor in coal mine.At industrial frequency voltage of 4 ̄6kV and current of 100 ̄1000A it is verified that voltage error is less than 1% and current error less than 3% of optic fiber electric parameters sensors.It is pointed out that improving current detection accuracy is the powerful way to improve optic fiber and decrease pre amplifier noise and collect magnetic fields efficiently.
