The movement of know-how or technical knowledge from one organization to another known as knowledge transfer in literature is considered to be one of the most important components of the strategic plan of a research institute. Despite the fact that INCESA (Research Hub of Applied Sciences, University of Craiova) is a young organization, it already counts an important number of collaborations with...
This paper summarizes the results of a three-phase load flow analysis case study. This work was part of an overall energy systems modeling and analysis effort designed to develop a validated power flow study that facilitates understanding of power flow concepts for the present distribution networks operating in asymmetry conditions. To simplify data collection requirements and illustrate key concepts,...
This paper presents the principle of a load flow algorithm adjusted to asymmetrical operation of the three-phase distribution networks. The algorithm is based on an iterative procedure, which is independently applied on three equivalent sequence networks and uses a phase-to-phase equivalent model for unbalanced loads connected to the analyzed network.
This paper deals with the assessment of reactive powers related to network users for payment and compensation purposes. The drawbacks are evaluated and compared with the benefits for voltage regulation, according to Romanian regulations. Theoretical skills are combined into one organic methodology, and an in-house software package for reactive power assessment is built. This is based on sensitivities...
This paper deals with two categories of congestion management methods. The dispatch method is analyzed in two versions: static and differential, each one applied to outputs or to loads. The static method used the contributions to congesting flows, whereas the differential counts for the impact on flows before and after congestion management. The results for static and differential cost allocation...
This paper has focused on power quality investigation based on complex measurements in the substations of local distribution networks. The distribution network area chosen for the present analysis is of interest for a further renewable sources connection. For the power quality assessment a new type of information report is discussed as viable future alternative for network operator. According to this,...
The actual state and operation of the Romanian power system ask for a certain expertise in detecting the causes of electromagnetic perturbations and their evaluation in power grids. Consequently, all the aspects regarding the power quality issues became a common characteristic of the power systems' curricula within Romanian power engineering faculties. The students attending these classes are involved...
Fuzzy logic is a convenient method for expressing vague categories of information and provides the tools for performing logic operations with these information by using of fuzzy sets. In this work, the fuzzy system was developed for analyzing fatigue aspects of the laminated composites used in manufacturing of insulating components of the new generation electrical equipments. Using experimental data...
The reactive power is the major drawback of the AC electric grids. This paper proposes a performance index, “Q/loss”, based on the energy loss share of the MVAR flows. If computed with powers, the performance index is time-dependent and characterizes one grid operating regime. Calculated on energy basis, it stamps the quality of the MVAR control over a period of time. As outlined by simulations conducted...
Constrained by their companies' budget limits, the Romanian industry recruiters are oriented to graduates with high-tech systems management knowledge, and who are also trained to make both technical and business decisions. These new employers' requirements assume an extended list of graduates' competences: project management potential, ability for teamwork, and of great importance interpersonal skills...
