Fig. 4 is that electric energy governing device 9 lays schematic diagram.As electric automobile accesses flexible direct current power distribution network 1 on a large scale, greatly
The randomness of load switching may cause the voltage flashover of DC distribution net 1, voltage deviation, voltage dip temporarily to rise, when serious very
System crash can extremely be caused.So as to cause, circuit is damaged, capacitor burns out, dc circuit breaker and relay misoperation, load burn
Etc. equipment end failure.In addition, by electric automobile access on a large scale the quality of power supply pollution that DC distribution net 1 produces can also affect straight
Stream 1 normal operation of power distribution network, periphery accumulator of electric car and other loads, can cause the electricity for being filled with accumulator of electric car
Energy quality is affected, and causes the service life serious curtailments of accumulator.Monitoring modular 4 is put and is located near electronic by the method
The signal that electrical power sensor is collected is fed back to signal acquisition module 5, signal by the distribution line end of automobile charging pile 3 in real time
Acquisition module 5 will gather signal and be converted to, if the quality of power supply is less than valve
Value, Data Analysis Services main website 6 will be assigned instruction and make its action to electric energy governing device 9, while converting digital signals into phase
The actual value that answers sends on-line monitoring terminal to.Its electric energy governing device 9 is also installed in the distribution near electric automobile charging pile 3
Line end.
Presently preferred embodiments of the present invention is the foregoing is only, not in order to limiting the present invention, it is noted that all
Any modification, equivalent and improvement for being made within the spirit and principles in the present invention etc., should be included in the guarantor of the present invention
Within the scope of shield.
