Large amounts of alarms coming into control center when faults occur have harassed operators for a long time, especially when there are false alarms, missing alarms or multiple faults. An online intelligent alarm-processing system based on abductive reasoning network (ARN) is developed to deal with the alarms automatically. Models and real-time data of the power system are collected from both supervisory...
The energy management system (EMS) is the core of an electric power control center (EPCC) to manage and control the power system in a secure and economical way. Because the power system nowadays is large and interconnected (in the space dimension), the operational state is continuously varying (in the time dimension), and the control objectives are numerous (in the dimension of objectives), an EMS...
The classification, reasons and countermeasures of the computational failures of continuation power flow are proposed in this paper. The computational failures can be divided into the turning point failures and the non-turning point failures. The reason of the turning point failure is that the global parameterization such as arc-length or pseudo arc-length parameterization cannot overcome the singularity...
