A new and intelligent operation assessment system in simulation training of substation
Most nation-wide substation simulation systems only provide the function of generating dispatch operation sheet and the new personnel always fail to cope well with the operation for the vital network and the complex dispatch task due to their lacking of practice and shortage of intensive memorization. It's necessary to enhance the training intensity while the new function should be implemented for optimizing in order to promote the training effectiveness. For above problems, the envisage design for the assessment system in this paper is presented based on self-invented substation simulation system of generating dispatch operation sheet.
Reason analysis and precautions of blackout in 220 kV substation
One 220kV substation blackout for the reason of bus relay protection equipment’s misoperation. According to the status of related equipments, monitor messages and the fault wave graphics and data, error action of bus relay protection equipment is caused by the fault of switcher’s location. After investigating the manual of voltage switcher and the map of bus relay protection equipment, one fault is found that the "switch relays relay on at the same time" alarm can’t be send out when I bus and II bus secondary voltage is paralleled non-normally. The monitor circuit for "switch relays relay on at the same time" signal has been improved, and the security of power grid has been enhanced.
A personal computer based interactive software for power system operation education
The use of personal-computer-based interactive software to aid instruction in power system operations is described. The software was designed to be used as a teaching aid for the course power system operation at National Taiwan University. The main programs included in the package were short-term load forecasting and unit commitment. Other supporting routines included power flow analysis, static security assessment, small signal stability analysis, and transient stability analysis. To promote the students interest in the course, a user-friendly interface and interactive windows have been developed. The integrated software package proved to be useful for educational and research purposes. >
