The Study Of Power Remote Equipment Based On Parallel Bus

With the rapid development of the national economy, Ultrahigh voltage power system automation in the power system, high, medium voltage, low voltage, the voltage levels have been significant developments. Of flexible, affordable, functions, the strong anti-interference capability far as the electricity sector gradually moving terminals installed the new requirements.The power Remote Terminal Unit equipment based on Parallel Bus arouse the more and more many power equipment firm and the power consumer taking seriously simplely owing to that concurrence highway electric power moves far,because of flexible configuration ,cheaper price, The software programming is simple. The main body of a book the main design to concurrence highway is make a little theoretical analysis, and face to face electromagnetic compatible and so on aspect makes a few other studying analysis.By the theoretical analysis to distant transmission line effect in the design moving device concurrence highway of electric power,point out the square law resolving the signal completeness problem: Lie in the matching carrying out the signal source end impedance and terminal impedance; Reduce the signal rate under the situation of satisfying a functional requirement to the full.Face to face, the source holds in-line matching , terminal parallel connection mates , Davey mates in the south , the RC network mates , the diode mates waiting for the excellent shortcoming of various circuit impedance match method to carry out analysisSum up the method analysing automatic control on electrical power system moving compatible design of the device electromagnetism far: Shielding; Filtering; Grounding; Technology keeping apart; Balanced transmission.Essential being insulated designing that: Attention climbs electricity distance; Design common mode wave filtering capacitance value according to demand of electric system to leakage of electricity stream.Simulate amounts to every exchange moving a device far importing; Direct-current simulates amounts importing; Switch amounts import; Switch amounts output; The detailed principle simulating amounts output waiting for the fundamental function plug in connector to be in progress designs and analyses direct-current. The "chip phenomenon producing choosing" being hit by Chang appearing carries out analysis on electron product, and proposes that to resolve way: The sequence raising the data building-up time and retention time leaves amounts.
