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.
DESIGN AND IMPLEMENTATION OF A TRAINING SIMULATOR FOR SUBSTATION CONTROL CENTRE
A new operator training simulator for substation control center was presented. This simulator could wholly simulate two kinds of typical monitoring systems, namely the SCADA. Using this simulator the detailed simulation of the power grid, where the control center located in, the 500kV, 220kV and 110kV substations possessing different features, which were controlled by the control center, and the associative substation automation systems could be conducted. Therefore, the integrated simulation consisting of control centre simulation, substation simulation and power grid simulation was realized, thereby, the operation process of the whole control center could be fully simulated. The developed simulator is put into operation at a certain power supply company, and good training results was obtained.
The Determination of Physicochemical Characteristics of Biodiesel and Its Blending Oils
The viscosity,combustion heat,sulfur content,carbon residue,ash,flash point,moisture and cetane value of biodiesel and its blending oils with diesel were determined.The influence of temperature on the viscosity was studied,and the physicochemical characteristics of biodiesel and its blending oils were compared with diesel.The results indicated that biodiesel and its blending oils had some superior performances and good application prospect.
