Power module DSDP150 Controller/driver board
According to the distribution system diagram (briefly), the system has two main power supply, one power supply and one backup, which is a typical one master and one slave power supply system. The interlocking relationship of the system is as follows: When one main power supply, the contact bus can be combined or separated; When contacting the mother union, the other main advance cannot be combined; When two power supplies are available, the contact bus is disconnected. When one main feed loses power, the other main feed automatically enters power supply. When designing the control program, we design the system operation into three operation modes, that is, the main one power supply mode, the main two power supply mode, and the dual power supply mode. The automatic emergency processing program is included in the main one and the main two power supply mode.
Cabinets 1 and 13 are the main input 1 and 2 switchgear, cabinets 2 and 12 are the reactive power compensation switchgear, cabinets 7 are the liaison bus switchgear, and other cabinets are the feed switchgear.
5. Programming instructions
Sucosoft S40 programming software of IEC1131 standard under Windows environment is used for PLC programming. The programming has three ways: instruction, ladder diagram and function module. In order to facilitate communication, we generally use command mode. In the main control program design, according to the function of the day module design, the main program call, easy to on-line debugging and debugging. Although there are many PLC modules on the system bus, because its address is unique, reading and writing is as convenient as accessing the local I/O port. Both the closing coil and the opening coil of the circuit breaker use pulse signals, and the pulse width cannot be too wide, and Is is appropriate. Carefully deal with the relationship between the PLC program and the electric button switch to ensure that the two do not affect each other. Otherwise, it will cause the phenomenon that the electric and manual can not be closed or separated continuously. The communication byte definition for the master and the intelligent slave must be the same.
6. System characteristics
