The Application Of Meta-congnation Theory In Substation Training Simulation

The running condition of substation affects security and supply quality of the power system. In order to ensure power systerm to run safely and reasonably, it's necessary for substation operation staff to be trained in the substation training simulation which combinded computer technology and electric power system technology.In the view of less consideration to human thought and little doctrinal during the verification of switching operation and accident disposal, the meta-cognition theory, which includes knowledge, experience and adjusting, is introduced into the switching operation and accident disposal training to enhance its flexibility. The operation rule knowledge base, which is guided by meta-cognation theory, is founded according to the substation operation rules of switching operation and accident disposal, in the view of the exchangeable and independent operation. At the same time, the strategy which solves the operation dithering problem is built in the operation rule knowledge base.The specific method adapts to online evaluation and corresponding score system on the foundation of operation and accident disposal rule knowledge base. To differ from the independent and reminding operation, freezing and free-freezing mechanism is introduced during the online evaluation. Fuzzy score is given according to the factors such as freezing reason, freezing times and the rate of freezing success and the teachers can fully master trainees's understanding condition about knowledge according to the recording files and raise corresponding training strategy. This evulation system can reflects trainees's mastering and disposal level about operation and accident disposal knowledge to some extent.The training system can improve the technology diathesis of the substation operation staff and becomes the powerful anti-accident tools, besides, the mind has been put into practice in the Substation training simulation system of BaJiaZi .
