Indices for Assessing and Measuring Short and Sustained Interruption to Quantify Power System Performance
نویسندگان
چکیده
This paper presents the main results of a benchmarking survey for Northern Power System in Vietnam to measure the Power Quality and Reliability in regard to short and long-term interruption. The survey was conducted in 28 provinces and cities divided into four groups to compare: mountainous vs. delta areas and industrial vs. agricultural areas. The evaluation of power quality is based on reliability indices SAIFI, CAIFI as well as RMS voltage variations indices SARFI. Although the comparison of such indices was the main issue, several other issues were analyzed to assess which phenomena are most complained by customers and the customers’ solutions. The study has resulted in the collection of database for Vietnamese electrical engineers and experts to have a good picture and raise the awareness of Power Quality. Keywords-power quality survey; short interruption; sustained interruption ; SAIFI; SARFI; CAIFI; power quality solution

Indices for Assessing Utility Distribution System RMS Variation Performance
For many years, electricity distribution companies have used sustained interruption indices as indicators of the reliability of service provided on their systems. Today, however, many electricity consumers are adversely affected by more subtle voltage disturbances such as sags and swells. Many utilities are well aware of such service quality concerns and are implementing extensive monitoring sy...

متن کاملDevelopment and Validation of Sound Transmission Loss Measurement System for Measuring Muffler Performance
Muffler is a part of the vehicle exhaust system that absorb or reflect sound waves to reduce exhaust noise. One of the most important determinants of a muffler performance is the amount of attenuation that has on its input wave; this parameter is known as sound transmission loss. Four - mic standard test is one way to determine this parameter which is used in this paper. In this study, a test d...
