This paper focuses on black-start of power system with turbine based combined cooling, heating and power (CCHP) systems as start units. Firstly, the relation among inrush current, the capacity of CCHP systems and transformers are researched and summarized by building models and running simulations in PSCAD. Then three typical black-start cases are designed based on the distribution network, and simulation...
A novel compact bandstop filter (BSF) based on signal interference technique is presented in this paper. The designed structure consists of two bilateral transmission lines and one central series capacitor. Bandwidth and rejection level of the filter can be controlled by changing the circuit parameters. The equivalent model and a set of analytical formulas for the design of the new BSFs are provided...
