Simulation temps réel de dispositifs électrotechniques

Abstract : Industrial controllers are always subjected to parameters change, modifications and permanent improvements. They have to follow off-the-shelf technologies as well as hardware than software (libraries, operating system, control regulations ...). Apart from these primary necessities, additional aspects concerning the system operation that includes sequential, protections, human machine interface and system stability have to be implemented and interfaced correctly. In addition, these functions should be generically structured to be used in common for wide range of applications. All modifications (hardware or software) even slight ones are risky. In the absence of a prior validation system, these modifications are potentially a source of system instability or damage. On-site debugging and modification are not only extremely expensive but can be highly risky, cumulate expenditure and reduce productivity. This concerns all major industrial applications, Oil & Gas installations and Marine applications. Working conditions are difficult and the amount of tests that can be done is strictly limited to the mandatory ones. This thesis proposes two levels of industrial controller validation which can be done in experimental test platform : an algorithm validation level called Software In the Loop (SIL) treated in the second chapter ; a physical hardware validation called Hardware In the Loop (HIL) treated in the third chapter. The SIL validates only the control algorithm, the control law and the computed references without taking into account neither the actual physical commands nor the physical input feedbacks managed by the Input/Output boards. SIL validation of the system where industrial asynchronous motor is fed and regulated by a three level Variable Speed Drive with a three level voltage source converter is treated in the second chapter with a particular modeling approach adapted to such validation. The last chapter presents the HIL validation with various hardware implementations (Field Programmable Gate Array (FPGA), processors). Such validation checks both the control algorithm and the actual physical Input/Output signals generated by the dedicated boards. Each time, the modeling approach is chosen according to the hardware implementation. Currently this work has contributed to the system validation used by General Electric - Power Conversion © (GE-PC) as part of their validation phase that is mandatory for Oil & Gas projects and Marine applications
