The function of automatic switching system, the city electricity, unit two:



The system has two power city electricity, set automatic switching power supply function, mainly realizes the automatic switching power supply mains and unit.   Normal state, city power supply system has the priority function, when the mains power failure, the system can set automatic switching side, by the unit to the automatic load power supply; when the restoration of normal utility power system, automatic switching of the electric side, municipal electric power to the load automatic power supply, with the City Electric preferred power supply function.







According to the number of generating units and the city electricity is different, can be divided into: switching single group and one city power switch, single and double electric group switch unit with single, double, double city power switching unit with double city power.   Their functions are as follows:







Switching A. single group and one of the city power:



Parameter display function: mains voltage, the generator voltage, load current.



State display function: normal / fault, generator running / fault, electric / generator load.



Manual control function: manual / automatic / repair, generator / the city power load.



Automatic control function: fault, delay confirmation (adjustable time), issued instructions starting unit, unit start normal operation, the generator load; the city electricity recovery, delay confirmation (adjustable time), the city power load, no-load running 3 minutes (adjustable) after the automatic shutdown.







Switching B. single group and double electricity:



Parameter display function: a road, two road, the city power voltage mains voltage, the generator voltage, load current.



Status display: a road normal / fault, two road normal / fault, generator running / fault, a road two road, electric / electric / generator load.



Manual control function: manual / automatic / repair, master / selection, reserve city electric generator / road two road, electric / electric load.



Automatic control function: the main use of electricity failure, delay confirmation (adjustable time), the reserve city



Electric load; two electricity are failure, it sends the starting command, the unit starting back in operation, the generator load; the city electricity recovery, delay confirmation (adjustable time), the city power load, no-load running 3 minutes (adjustable) after the automatic shutdown.







Switching C. double unit with single city power:



Parameter display function: mains voltage, voltage, a number of No. two generator generator voltage, load current.



State display function: normal / fault, a number generator / fault, No. two generator running / fault, the city electricity / number one generator / No. two generator load.



Manual control function: manual / automatic / repair, main / standby generator, a generator choice / No. two generator / the city power load.



Automatic control function: fault, delay confirmation (adjustable time), start with the main unit instruction, main unit start running normal load; such as the main units in starting or fault occurs in the process of operation, automatic start standby unit, the normal operation of standby unit after starting with load; city power recovery, delay confirmation (adjustable time), the city power load, no-load operation minutes (adjustable) after the automatic shutdown.







Switching D. double unit with double electricity:



Parameter display function: a commercial power voltage, two city road, electric voltage, voltage, a number of No. two generator generator voltage, load current.



Status display: a road normal / fault, two road normal / fault, a number generator / fault, No. two generator running / fault, a generator / No. two generator / a road in the city of electric / two road in the city of electric load.







Manual control function: manual / automatic / repair, main / standby generator selection, the active / standby hand city power selection, number one generator / No. two generator / a road in the city of electric / two road in the city of electric load.







Automatic control function: the main use of electricity failure, delay confirmation (adjustable time), spare the city electricity load; two electricity are failure, delay confirmation (adjustable time), start with the main unit instruction, main unit start running normal load; such as the main units in starting or the fault occurred in the process of operation, automatic start standby unit, the normal operation of standby unit after starting with load; electric recovery, delay confirmation (adjustable time), the city power load, no-load running 3 minutes (adjustable) automatically.







The system adopts a Sino foreign joint venture love Czech ATS switch, realize electromechanical interlock to ensure reliability of operation.







Since three, and the car, automatic frequency and load adjustment system function:



The system has the function of grid connected A. manual / automatic grid / "0" position three sets of system and selection.



When the system is in the manual car condition, through the realization of two units of manual synchronization table.   Parallel operation, through the automatic frequency and load adjustment device, the realization of the unit operation process of automatic frequency modulation, automatic load regulation.







When the system is in the "0" state in the automatic mode, the two units in the city after the power failure at the same time start the unit, to realize the automatic cast net power supply only a delay unit, another unit 3 minutes downtime.   If the net unit has been voted the failure occurs, immediately start the other units and cast the net power supply.







B. when the system is in the automatic and state: in automatic mode two units in the city after the power failure and start the unit, to realize the automatic cast net armor units, when the power load is smaller than a rated power, delay B unit 3 minutes downtime, when a unit has been in operation for 8 hours of continuous work, B units will start immediately, achieve two units of automatic synchronization, and the power supply load is transferred to the second unit, a unit from a network, and a 3 minute delay shutdown.







C. when the power supply load for 1 minutes more than a rated power, the other units will start immediately and grid connected power supply.   The frequency and load control device to ensure the two units of uniform distribution of load.







This function can be programmed according to user requirements.







The D. system and it is the reverse power protection.   The system uses high reliability of electrical products, automatic control, automatic start, automatic cast net, automatic back network, automatic shutdown and automatic control, industrial computer using industrial control computer PLC system, ensure the operation reliability.







E. automatic paralleling device, automatic frequency and load adjustment device, adopts the quality reliable products.
