1 Scope of this document

The Goal Oriented Training Programme – Power Supply Engineering (GOT-PSE) aims to train five researchers in the field of power supply (PS) engineering [1]. The participant Associations must develop a collaborative training program based on a comprehensive set of courses and shadowing activities on the operation of the facilities present in each laboratory. The trainees will have the opportunity to gain experience on the operation and maintenance of the present electrical plants and experimental devices and in the development of new on-going design activities.

The present document describes the common courses and activities organized by ENEA for the GOT-PSE program in the years 2010, 2011 and 2012.

The present document is periodically revised with the update programs of future courses including their tentative schedules and with the summaries of the performed activities.

2 General principles of ENEA courses

The courses are structured in modules. As summarized in Table I, the course modules can be classified in 3 different types. Table I also introduces a color code to distinguish the type of module according to this classification. The expected duration of each module is about 45 minutes, including a reasonable time for questions/discussion. Longer activities can be arranged in two consecutive modules.

TABLE I CLASSIFICATION AND DESCRIPTION OF THE COURSE MODULES.

Type of Module Code Module Description

Lecture LM

It is performed by a teacher in the conventional style for University lectures, lessons, seminars. The lectures include the features of particular software environments and techniques useful in power supply and nuclear fusion applications.

Visit to plants and laboratories

VM

The visits to the installation show the practical implementations and specific technologies of power supplies. The visits mainly concern the FTU power supplies and the other research projects active in the Frascati Laboratories.

Experience on design and simulation

EM

The courses introduce a wide set of software environments and techniques to model, simulate, design, control and manage electrical and electronic systems. The experiences present some examples of their use, including the possibility for the trainees to approach some numerical designs and simulations with the support of a mentor.

Visits to plants and laboratories (VMs) are organized when the access to the plants is allowed. Delays

and cancelations of the VMs would be possible due to problems arose in the meanwhile or for any other safety or security reason.

In principle, each cycle of annual courses takes 2 weeks. The weeks are considered complete. The travels to/from Frascati should preferably be in the previous or following week or weekend. However, the activities in the first (Monday) and in the last (Friday) day may be lighter to allow late arrivals and early departures. The first day also includes welcome activities as general and logistic information. The organization is quite flexible, also in order to try to take into account the specific needs of the trainees. To improve the quality of the organization, at the end of the courses, the trainees are kindly requested to fill a Course Evaluation Form.

The courses are supervised by ENEA mentors and may involve, as coordinators of as specific topic or as teachers, both ENEA and external experts.

The training lectures and the presented subjects are supported and integrated by syllabi, slides, references to published documents (papers, books, reports, standards, regulations, and so on) and additional materials reporting the state of the art. All the didactic material is uploaded in the GOT-PSE website https://www.igi.cnr.it/gotpse, developed by Consorzio RFX. The access to such material in the website is restricted to the trainees and to the GOT-PSE mentors and partners. The material presented during visits, practical work or shadowing (as detailed schemes or procedures) is not generally available for the trainees. Some exceptions to the above rules might be identified.

3 Organization, structure and time schedule of the ENEA Courses 2010

Maurizio Santinelli was the ENEA Contact Person and the ENEA Course Coordinator for the year 2010. Two types of courses were organized. They are classified as Course A and Course B. Each course was scheduled over an entire week: the Course A was from Monday 5 July 2010 to Friday 9

July 2010; the Course B was from Monday 12 July 2010 to Friday 16 July 2010. The Courses were divided in modules. The Course A included theoretical lectures (LMs) and experiences

on design and simulation (EMs). The Course B included modules with visits to plants and laboratories (VLs). The visits will be organized to give a general outlook of the systems (included controls and measurements), followed of an in depth control of the power supply starting from a vis-à-vis examination of the equipment.

The Fridays were particularly devoted to a general review of the topics covered during the week. Moreover, the trainees were kindly requested to fill a Course Evaluation Form at the end of both the courses.

The material presented during the training courses is generally available to the trainees. Each course day was directed by a (ENEA or external) coordinator. The names of the coordinators are

reported in Table II. The objectives and topics of the courses are extensively listed in the following sections.

4 Preliminary organization of the ENEA Courses 2011 (tentative)

Due to the retirement of Maurizio Santinelli, Alessandro Lampasi substituted him since December 2010 [3] and was the ENEA Contact Person and the Course Coordinator for the year 2011.

Two types of courses will be organized: the former concerns the software ETAP, the latter the principles of poloidal and toroidal coil power supply (CPS). The courses are classified as Course ETAP and Course CPS. The Courses will be divided in modules.

The Course ETAP in the first week will be focused on the ETAP software. ETAP is a comprehensive analysis tool for the design, simulation, and operation of generation, distribution, and industrial power systems [5]. The Course ETAP will include a practical experience (EMs) on the implementation of ETAP code, consisting in the ETAP simulation and study of an alternative MV distribution scheme (20kV) for the ITER Steady State Electrical Power Network (SSEPN). The experience is essentially based on the ENEA activities developed in the framework of the EFDA Contract “Supervision and Collaboration to the Detailed Design Activities of the ITER SSEPN”.

The Course CPS in the second week will deal with the power supply of tokamak coils. A particular emphasis will be devoted to the FTU power supplies. The course will be divided into theoretical lessons (LMs), examples of numerical simulations of CPS (EMs) and visits of the FTU power supply systems (VMs).

Visits to plants and laboratories (VMs) will be organized when the access to the plants will be allowed. Delays and cancelations of the VMs would be possible due to problems arose in the meanwhile or for any other safety or security reason.

The material presented during the training courses will be generally available to the trainees. The courses will be organized covering 2 consecutive weeks in Frascati. Each course was scheduled over

an entire week. A tentative schedule of the courses is fixed starting since 11 October 2011. A preliminary overview of the course topics and organization is reported in Table V.

5 Preliminary organization of the ENEA Courses 2012 (tentative)

A two-week cycle of courses will be organized. The idea is to present the test and commissioning activities of a real power supply project performed

in the ENEA laboratories. The best candidate project could be the body power supply (BPS) prototype present in the ENEA

laboratories. Firstly, the BPS final design will be analyzed through some simulation models. Then, the trainees will approach a commissioning phase. In particular, the trainees will verify the prototype performances agreed in the technical specifications by executing some experimental tests (on a dummy load).

Alternatively, the experimental activities of other ENEA power supply systems could be investigated.
