Short-circuit fault current suppression is a very important issue in modern large-interconnected power networks. Conventional short-circuit current limiters, such as superconducting fault current limiters, have to increase additional equipment investments. Fast power electronics controlled flexible AC transmission system (FACTS) devices have opened a new way for suppressing the fault current levels,...
On-load tap changer (OLTC) is essential in regulating the operation status of power transformers employed in modern power systems. While exploring power flow analysis, electromagnetic and electromechanical simulations by using the on-load tap changer, it is found that inaccuracy problem may occur with the assumption in conventional transformers that tap positions only affect the turns ratio parameter;...
With the integration of more and more nonlinear components such as the power electronic devices in modern Energy Internet systems, traditional electromechanical transient simulation would not be able to accurately reflect the dynamic response of modern power systems. System level full electromagnetic transient (EMT) simulation could be a possible supplement to the power system simulation. However,...
With the widespread application of HVDC technology, power system harmonics generated by power electronic equipments can no longer be neglected. For example, the real-time current signal processing for protective relays or PMUs might be deeply affected by harmonics. In order to tackle with the accuracy for relays and PMUs, the inter-harmonic source for short-circuit current is theoretically analyzed,...
