Analysis of the Harmonious in Chongming Power Grid Connected with Distributed Resources
Lots of distributed resources have been connected to Chongming Power Grid in recent years,which makes Chongming Power Grid a typical power system.The？distributed generation can improve the comprehensive utilization of resources.It is helpful not only to Chongming Island＇s environmental protection,but also to Chongming Power Grid＇s safety in power supply.It can be concluded that the distributed generation has good performance in terms of economic,environmental protection,energy-saving,security and reliability.The operation status of Chongming Power Grid＇s distributed resource is introduced in this paper.Two different cases＇ data collected by on-line measurement devices show us the characteristics of harmonious caused by different distributed resource in Chongming Power Grid.The harm and suppression of the harmonics is also introduced in this paper.According to the prescriptions,the influence of the distributed resource in Chongming is within the permission.
