Summer School

Power electronic converters on transmission system from fundamental considerations to practical applications

L2EP : Laboratoire d'Electrotechnique et Electronique de Puissance - CE2I

11 – 13 July 2022

Objective

The number of power electronic converters is increasing quickly in all the different parts of the grid. The electrical power system is moving from the “electromechanical world” to the “power electronic world”. The aim of this course is to contribute to build a bridge between the two worlds by using simplified models of power electronic converters and by integrating the key parameters and needs of the power system in the control design of the converters. The control algorithms will be built step by step starting from fundamental considerations about physics and introducing progressively the different functionalities required for a converter connected to the grid. The classical grid following control will be addressed and its limitation highlighted but the focus will mainly be done on the grid forming control. From these fundamental analyses, some practical applications will be derived such as wind turbine control, storage or HVDC systems. The participants will progressively build their own control by using predefined models of converters.

Target Audience

The target audience is Phd students working in power electronic applied to power system and people from the industry working in the same topic.

The models of power electronic converters will be simple enough to be understood by any person with some basic knowledge about electrical engineering and control.

Teaching method

The program of the course is a mix between some theoretical contents closely connected with some practical simulations on Matlab/Simulink and Simpower system. All the simulation files can be loaded on its personal computer or run online by using Matlab Online (in this case, computers will be available). These simulation models will be freely available and may be used freely for other applications. Several speakers from industry will also propose some conferences in order to bring their practical experience. All the different model parameters will be using some realistic parameters drawn from practical data.

PLUTON

Identification:             “Power amplifier for ultra-fastAC/AC conversion” 

  • Context:

To insure the security and reliability a complex and wide coverage tests must be carried out during the whole life-cycle of the products in such industries as power production, aviation, electrical vehicles and railways. The power hardware in the loop or HIL simulation is more and more used to reduce testing costs and protect the real hardware from faulty controllers and in faulty condition tests. The electrical power systems such as drives and converters have a very fast dynamic and cannot be emulated using classical HIL equipment. The IRIS and PLUTON projects aims to develop new power hardware in the loop by exploiting new power converter topologies coupled with the Field Programmable Gate Arrays (FPGA) computing capability for drastically decreasing the simulation time steps allowing the real time simulation of the electrical power systems.

  • Aims:
    • Development of ultra-fast AC/AC conversion power amplifier for Powerhardware in the loop applications.
    • Coupling this power amplifier and the IRIS solver. 
  • Lasting:           since February 2017

IRIS

Description:

The Integration of Real time simulation on FPGA components or IRIS project is the joint effort of EPM laboratory and SPHEREA Test and Service company aimed to develop a new real time simulation system for power electronics and electrical machines based on a custom fast computational hardware implemented in Field Programmable Gate Arrays.

The product testing and maintenance is an important part of its life cycle in the industries with high security and quality demands such as aerospace, transportation or energy production. It allows reducing the risks of accidents, prevents financial losses due to systems failures in energy production and to increase safety. The testing can be very costly for big and complex systems such as an airplane or an electrical station but, although necessary, it can be replaced by a real time simulation at the first stage of the controllers and subsystems verification. In some cases, the testing on the real hardware can be even impossible if a response to faulty conditions is to be checked. The hardware in the loop simulation allows carrying out integral tests of the control systems and independent subsystems without connecting to the actual real-world equipment to greatly reduce the costs and damage risks.

The conventional HIL simulation systems doesn’t allow real time simulation of systems with very fats dynamics such as electrical power systems and machines. The IRIS project is centered around solving the dynamics equation of electrical systems and its acceleration with FPGA/System on Chip. Currently it includes the solvers for generic linear electrical systems based and power electronics the augmented nodal method, and synchronous electrical machines based on state space modeling, but additional type of solvers are planned to be developed. For both these methods a lot of computational power is required if fast real time dynamics simulation is to be achieved. Form the other point of view, the real-time simulation requirements impose the constraints on the loopback response latency. 

To respect these constraints the IRIS project uses hardware computation acceleration and input outputs control base on FPGAs – electronic components allowing to build reconfigurable digital logic circuits. Compared to conventional microprocessors they provide much larger flexibility and optimization of computation pipelines and compared to such devices as GPU they allow hard real time determinism insuring that a proper signal will be sent in the proper place and at the correct time which is very important for the communication with tested equipment and controllers. 

The IRIS simulation system has a modular architecture with asynchronous simulation modules designed for the specific electrical system simulation. The simulation modules are controlled and configured from the system on chip with an ARM core which is also used for host PC communication. This allows online configuration and reconfiguration on the fly to treat non-linearities and slow dynamics that can also be simulated on software part. 

The solvers developed in the IRIS project can be used for simulation of electrical power systems for the first stage testing and verification. It can be applied for testing and verification of power production, onboard power grids, electric propulsion and mechatronics in aerospace, automotive, railroad and power production industries.
