Module 3 THE POWER QUALITY, IN CASE OF WIND POWER PLANTS CONNECTION AT THE NATIONAL POWER SYSTEM. 1 INTRODUCTION The connecting of wind power plants at the electrical power networks and the operating specific conditions of these can determine electromagnetically disturbances into the networks to which are connected to, that influence the power quality parameters into the connecting node if adequate measures are not adopted for limiting the disturbances. The deviations from the voltage quality into the electrical network to which the wind power plants will be connected to can lead to decreasing of their performances and, in some cases at disconnecting by protection system of the respective wind power plant. During a disturbance in the electric power network, the wind power plants/units disconnecting may increase the harmful effects on the power system performances. Generally, when it is connected a wind power plant/unit it is required to be sized so as to cope with the disturbances which appear in the grid. 1.1 General aims This module’s general aim is to provide the attendants the basic knowledge about the power quality and the electromagnetically disturbances produced by the wind power plants, which may affect the power quality into the electrical networks to which are connected to and to familiarize them with the requirements of the Technical Codes for wind power plants to not affect the safe operation of NPS. The aim is achieved through 6 didactic sections, presented at point 2.2 from curricula. 1.2 Target groups This module’s target groups are: investors, consultants, designers, electrical installations building up or installation work contractor, managers and specialists from the electricity generation companies based on renewable power resources, respectively from the electricity companies, responsible with the initiation, financing, designing, implementation/performing, operating and maintenance of wind installations, from equipment sellers and services, as well, who intend to increase their knowledge in this field. 2 SPECIFIC AIMS AND TOPICS The pathway of module consists of a 2 days seminar, subdivided in sections (with different duration), with these contents and related aims. 1st day Contents
Aims
Introduction into power quality. Parameters that allow the assessment of wind power plants impact on the power quality. Provisions of Technical Codes of transmission and electricity distribution electrical networks. The first day aim is to provide the attendants the basic knowledge about power quality and parameters that allow the assessment of wind power plants influence on power quality. Also, there are analysed several provisions proposed for the National Technical Codes of transmission and electricity distribution electrical networks and they are compared with some provisions of the Technical Codes in Europe.
2nd day Contents
Aims
Harmonics and interharmonics. Voltage fluctuations (flicker effects). The influence of voltage dips, short interruptions and overvoltages from the electrical network on the wind power plants. The measuring of power quality. During the second day are provided the basic knowledge about the electromagnetically disturbances produced by the wind power plants, which may affect the power quality into the electrical networks to which are connected to. Also, there are presented requirements for equipment for power quality measuring and standardized procedures of measurement and aggregation of the measured data.

The didactic tools which will be used by the lecturers will be: − Blackboard; − Video-projector; − Pointer; − Notebook. The lecture room will be suitable to allow the use of all the above listed didactic tools. Each user will receive, during the registration, a folder containing: − course program; − lecture notes containing all or part of the lecture slides. At the end of each lesson/section the lectures will perform a Test referring to the taught knowledge.
