Description
Technical field
The utility model relates to a kind of output end voltage real-time compensation apparatus, particularly relates to the output end voltage real-time compensation apparatus under a kind of big current long range propagation condition.
Background technology
Along with equipment is to supporting power station significant power demand, man-machine environment demand, requires the generator end of electric power station system and the long range distribution of distribution output, can ensure the demand of equipping like this, the man-machine environment demand of operator can be ensured again, can execute the task under the environment of a low noise.The electric power transfer of big current, long distance, the pressure drop that the cable due to conveying produces, and change with the change of big current, cause the voltage fluctuation of output to change, bring potential safety hazard to the use of equipment.Stablize output end voltage, that improves equipment uses electrical stability.
Summary of the invention
The purpose of this utility model is to provide the output end voltage real-time compensation apparatus under a kind of big current long range propagation condition, this device is according to the drooping characteristic of Real-Time Monitoring transmission & distribution cable, to output end voltage real-Time Compensation, can realize under any load current condition, output end voltage is stabilized in the range of nominal tension.
The utility model is achieved like this, the output end voltage real-time compensation apparatus under a kind of big current long range propagation condition, it comprises voltage regulator, control module, voltage sample cable module and miniature circuit breaker; It is characterized in that: voltage regulator link control module; control module connects voltage sample cable module; voltage sample cable module connects miniature circuit breaker; described miniature circuit breaker provides the defencive function of sampling circuit; voltage sample point is arranged on output; feed back to control module through voltage sample cable module, control module detects sampled voltage and sends regulating command, and voltage regulator performs pressure regulation action.
Further, described voltage regulator and control module are arranged on generator end.
Further, described voltage sample cable module is arranged on power transmission and distribution cable-end.
Further, described miniature circuit breaker is arranged on output.
Operation principle of the present utility model is: side of generating set is provided with control module, after electrical power generators through transmission & distribution cable to power distribution station, traditional mentality of designing voltage sample is directly the output of generator, voltage close loop regulating system cannot do auto-compensation to the pressure drop that transmission & distribution cable produces, consider the pressure drop that transmission & distribution cable produces and electric current proportional, so artificial setting adjustment generator output voltage can't resolve the compensation problem that load dynamic change causes.Operation principle of the present utility model is that the part of transmission & distribution cable as generator is extended, the change in pressure drop real time reaction of transmission & distribution cable generation in voltage close loop regulating system, namely the voltage sample of voltage-regulating system point is arranged on output, voltage-regulating system then removes the voltage of regulation output end according to load voltage value, be equal to the pressure drop recessivation that transmission & distribution cable produces, no matter the voltage drop value that produces of transmission & distribution cable along with curent change how many, the voltage all-the-time stable of output is in the range of nominal tension.
Technique effect of the present utility model is: the long range distribution (>=100m) of output and generator end, the change of electric current causes output end voltage to change, by the application of this technology, can the regulation voltage of dynamic realtime, output end voltage is stabilized in the range of nominal tension.
