10 Integrated Smart Alarm General Framework Integrate Smart Alarm Visualization Risk Awareness Beforehan d Fault Analysis Online Decision Support Afterwards Researching on the online frame Co-processing of monitoring risk visualization awareness between and support analysis based the online platform technology weather accident and flexible concerning application analysis information and integration, about and Power grid the system operating accidents achieving application pattern, occurred the presentation achieving software(pas), in large the power visualization multi-dimensional achieving grid, achieving the the platform automatic awareness comprehensive and fast on decoupling evaluation accident analysis risk under of in platform order on the short grid to and aid circuit operating application dispatchers fault, state power data, dealing when unit and the trip, thus with fault the HVDC improving occurs risks in (high-voltage and advance. the giving openness theeffetive direct and current) expansibility. measures pole blocking, to eliminate and the the out-of-limit abrupt change ranges, on and power then improving flow and voltage, the emergency and assisting response to acquire by the the dispatch gird operating once the accident information of power timely grid and occurs. accurately. 10

11 Integrated Smart Alarm (Risk Awareness Weather Risk) Risk Factors Typhoon & Lightning & Rainfall & Fog Monitoring Measures Geographic & Weather Information & Risk Devices Preventive Measures Expected Fault Sets & Security Check External Weather Risk Devices Typhoon Improve the power grid capacity to resist external risks Security Check Expected Fault Sets 11

12 Integrated Smart Alarm (Online Fault Diagnosis General Framework) Hierarchical fault diagnosis architecture Flexibility Adaptive differences between different users of data sources. Open Each module can be flexible, integrated thirdparty results. Assurance the user's original results with the maximum degree,reduction of secondary investment 12

13 Integrated Smart Alarm (Online Fault Diagnosis High Reliablity) High Reliability Breaker s change Protect Signal Through the depth data mining of fault information, combining with the state variables and electrical variables, improve the accuracy of real-time fault diagnosis. Total Fault Signal General Criteria SOE Voltage & Current mutation Previous Now 0 Error Miss Accuracy 13

14 Integrated Smart Alarm (Fault Handle Decision Support) Proposed the co-processing between online fault diagnosis and PAS, achieving the comprehensive assement of power grid status when the fault occurs, solving the need to manually tedious operation of PAS,and thus improving the effciency of PAS. Complete by online auto sequence control Power flow off-limit Voltage off-limit Fault current off-limit Measures 14

15 Integrated Smart Alarm (Fault Information Hierarchical Display) Proposing the technolgy of hierarchical fault information, achieving the comprehensive alarm of power grid information which the fault occurs,solving the alarm information explosion after a fault and dispatching the problem that the key information can t quickly be accessed to.
