The large-scale application scenario of modular multilevel, such as STATCOM, flexible DC power transmission etc..Due to the complexity controlled, to controlling to set
Carry out real-timedigital simulation test before standby on-the-spot operation and seem more and more important.This checking not only includes the checking to principle,
Also include the checking to hardware and interface, therefore more and more stronger to the demand of equipment real-timedigital simulation.
The most large-scale modular multilevel power electronic equipment real-timedigital simulation mainly uses RTDS and RTLAB equipment
Complete.Due to varying of concrete equipment interface, simulator can not provide the interface meeting all devices, the most very
Difficult docking port is verified.And in the emulation of modular multi-level flexible direct-current transmission, often use aurora interface straight
Connect the master control borad with valve control device to be attached, and skip optical fiber transceiving plate.This can cause two problems occur: first, for
The program of master control borad is modified by adaptation this connected mode needs, causes software during emulation to be deposited with on-the-spot operation software
In difference.Second, the software on substantial amounts of fibre optic plate hardware and fibre optic plate cannot be carried out effectively verifying.
Utility model content
The purpose of this utility model is for above-mentioned the problems of the prior art, it is provided that a kind of real-time simulation environment RT-
The interface arrangement of LAB, this interface arrangement is without revising master control borad program for connected mode, and precision is high, it is possible to checking is many simultaneously
Pipeline equipment.
To achieve these goals, the technical solution adopted in the utility model is: include the master control borad being arranged on backboard
And several fibre optic plates, every piece of fibre optic plate is each equipped with multiple light receiving tube and multiple light-emitting tube；

Described each fibre optic plate controls equipment from different converter power modules respectively by the optical fiber of 8 50MHz
Connect.
Compared with prior art, this utility model master control borad uses jumbo fpga chip, it is possible to receive multiple simultaneously
The signal of fibre optic plate, unpacks to backplane signal, then is packaged into high-speed serial signals, multiple high-speed serial channels send.
In each control cycle, emulator returns module voltage and other status informations by HSSI High-Speed Serial Interface.To height in FPGA
Speed serial signal is unpacked, and is distributed to all of fibre optic plate, and these signals are distributed to every road converter power by fibre optic plate again
Module controls equipment.This utility model every piece fibre optic plate is configured with multiple light receiving tube and multiple light-emitting tube, it is possible to connect simultaneously
Receive multichannel converter power module and control device signal, and return multichannel feedback signal.Every piece of fibre optic plate passes through with master control plate
Independent high-speed serial bus is connected, and therefore the control signal on every piece of fibre optic plate can arrive master control borad simultaneously, it is to avoid
In parallel bus, master control borad must read the control signal of a fibre optic plate, could read asking of next fibre optic plate signal
Topic.
Accompanying drawing explanation
