Description
Technical field
The utility model relates to based on the online real-time simulation platform technology of RTLAB more particularly to it is a kind of based on RTLAB from
Resistance type MMC real-time simulation heterogeneous platform.
Background technique:
In recent years, emulation technology because it is many itself the advantages of obtain universal application, such as: controllability, economy,
Safety, without destructiveness etc..But the emulation of power electronics majority is all offline, it is at low cost although simulation accuracy is high,
It is that speed is slow, simulated effect depends on the quality of model.The full-scale investigation in laboratory will by hardware device, environment etc. it is some because
The limitation of element, can not simulate the working condition under some maximum conditions.And when due to building analogue system, designer's waste
Plenty of time in system setting and code programming, can not be absorbed in the building and debugging of model, can reduce efficiency of research and development in this way,
And the modification of later period model also can be fairly cumbersome.
However the requirement based on high efficiency and real-time on-line simulation, experimental selection build it is a kind of based on RTLAB from resistance type
MMC real-time simulation heterogeneous platform, it is big containing the network system emulation platform scale from resistance type MMC to reduce tradition, simulation efficiency is low,
A series of problems, such as real-time.
Utility model content:
The technical problems to be solved in the utility model: it provides a kind of flat from resistance type MMC real-time simulation isomery based on RTLAB
Platform, big containing the network system emulation platform scale from resistance type MMC to solve tradition, low, real-time of simulation efficiency etc. is a series of to ask
Topic.
Technical solutions of the utility model
It is a kind of based on RTLAB from resistance type MMC real-time simulation heterogeneous platform, it includes: host computer, FPGA and MMC control
Device, FPGA are connect with host computer by optical fiber；FPGA is connect with MMC controller by I/O terminal.
DC grid and AC network mapping on the outside of the host computer and MMC connect；The FPGA and MMC bridge arm circuit
Mapping connection.
The utility model the utility model has the advantages that
The utility model will decouple, MMC bridge to containing the network system from resistance type MMC from resistance type MMC circuit and power grid
Arm circuit and small step-length FPGA hardware real-time simulation, DC grid and AC network part on the outside of MMC then use in big step-length
Position machine Hardware Real-time Simulation is established a kind of based on RTLAB real-time simulation heterogeneous platform；Realize grid main circuit with from resistance type MMC
The parallel computation of bridge arm equivalent circuit；Improve simulation efficiency；It is connected between host computer and FPGA by fiber optic Ethernet, realizes number
According to synchronizing information, real-time is improved, solves traditional, simulation efficiency big containing the network system emulation platform scale from resistance type MMC
A series of problems, such as low, real-time.
Detailed description of the invention
Fig. 1 real-time simulation heterogeneous platform block diagram.
Specific embodiment
It is a kind of based on RTLAB from resistance type MMC real-time simulation heterogeneous platform, it includes: host computer, FPGA and MMC control
Device, FPGA are connect with host computer by fiber optic Ethernet；FPGA and MMC controller pass through I/O terminal Hard link.
DC grid and AC network mapping on the outside of the host computer and MMC connect；The FPGA and MMC bridge arm circuit
Mapping connection.
The upper external MMC controller of FPGA carries out the control of the submodule trigger signal in MMC circuit model；This
System parameters T chooses 50us, and k takes 25, t to take 20us, then the MMC bridge arm computation model based on FPGA receives upper every 50us
The emulation data of machine and the trigger signal of MMC controller, then bridge arm when 25 t subsequent with the step-length Continuous plus of 2us is electric
Road emulation data simultaneously can issue host computer.
Heterogeneous platform synchronize refer to host computer, FPGA and MMC controller every time interaction be all same time step data,
If the material calculation of host computer is T, the material calculation on FPGA is t, T=kt, and wherein k is constant integer.It is every pass through T time, it is upper
Machine calculates T0The emulation data of+T moment big step-length side, and FPGA calculates T0The emulation data of+kt moment small step-length side.This
When host computer and FPGA by fiber optic communication, MMC bridge arm circuit model running is on OP7000 FPGA board, network system side
It operates on host computer, and realizes data exchange on RTLAB emulation platform, and carry out online real-time simulation.
