The existing topology analysis are not convenient for network architecture optimization. Switchboard incidence matrix and load-switchboard incidence matrix with constraints for them to describe the radial distribution network are defined in this paper. To solve distribution network optimization problem, method to calculate the network attributes are proposed with the defined matrixes. A computational...
With the development of capacity and topology in shipboard power system, parallel running of multiple generators in single power station becomes an important configuration. The traditional protection method, with characteristic of off-line setting, sets the same values for several bus tie breakers. All generators would be step out while short-circuit occurs on bus-bar, which dissatisfies protection...
A three-phase copper bus bars arrangement in low voltage system is investigated. Each phase main conductor consists in one up to four sub-conductors with rectangular cross sections. The short circuit may introduce great hazardous forces. In order to ensure bus bars and power system operate in security, verifying of short-circuit dynamic stability should be made. Three methods of calculating short-circuit...
