transformer network
2.The current configuration state for main transformer of south electric network and several problems met in practical project were introduced. Some of special problems of main transformer protection were analyzed and discussed.
5.This paper applies Electronic Power Transformer(EPT) into the distribution network to optimize and control the voltage and reactive power synthetically.
6.New~type distribution transformer supervisory control system based on network communication with general packet radio service
8.This paper compares the performances of three communication networ ks of integrative automatic transformer substation, points out that the integrativ e automatic transformer substation base on CAN (Controller Area Network) and Eth ernet technique is the inevitable trend of the development of the field of trans former automation.
9.By analyzing systematically the production principle of the common mode noise which is the major factor affecting quality of the switch mode power supply,the decision is reached that the common mode noise is walking through coupling earth capacitance transmitting output, and then a practicable measure of restraining noise is put forward:screens are added between major switch tube and radiation, between transformer primaries and transformer script,or FRD can be selected with R C absorb network.
10.Distribution transformer remote monitoring terminal based on DSP TMS320LF 2407A and wireless module GR 47 is designed,which takes DSP as controller and GPRS(General Packet Radio Service)wireless network and Internet as communication channel to transmit teledata for remote monitoring of distribution network operational parameters and states.
