This paper studies the validity of the standard method in IEC 61400-21 for assessing the flicker emission from multiple wind turbines. The standard method is based on testing a single wind turbine and then using the results of this test to assess the flicker emission from a number of wind turbines. This study is based on the data from two wind farms, one with fixed-speed wind turbines and one with...
It is necessary to monitor and analyze the power quality firstly in order to solve the power quality problems in power system, and then the possible reforming project can be put forward for improving power supply quality. According to the actual situation in the region, a system approach to voltage sag monitoring and analyzing has been designed and developed. The system and its composition, software...
The assurance of the power quality supplied to consumers represents one of the most important issues that have to be fulfilled, related to substation ancillary services power supply sources. The aspects concerning the power quality are highlighted for the designed and planning of the substations belonging to the transmission network. Within the monitoring process several quantities are analyzed. The...
The Colombian Energy and Gas Regulating Commission -CREG- through resolution CREG 024 of 2005, requires monitoring some power quality disturbances in substations of distribution systems; the main objective of this resolution is determine electrical power quality supplied by the utility operators to costumers by means of measurements analysis. In this paper the authors proposes a computational tool...
