Patent number: 10922452Abstract: A digital simulation system of a power distribution network, comprising: a client and a server end. The server end is a simulation server cluster composed of several simulation servers; the simulation server cluster and the client are mutually connected through a communication bus, wherein the client is configured to use a DCOM component to invoke a simulation service provided by the server end, and the server end is configured to distribute a task to be processed to each cluster node. Constructing the above-mentioned digital simulation system facilitates an optimal planning and operation of a smart power distribution network, thereby improving the utilization efficiency and reliability of the smart power distribution network and reducing the loss of a power outage.Type: GrantFiled: June 30, 2016Date of Patent: February 16, 2021Assignees: CHINA ELECTRIC POWER RESEARCH INSTITUTE COMPANY LIMITED, STATE GRID CORPORATION OF CHINAInventors: Keyan Liu, Wanxing Sheng, Yinglong Diao, Jiangang Tang, Xueshun Ye, Kaiyuan He, Dongli Jia, Lijuan Hu

Patent number: 10825112Abstract: A method of predicting the operation reliability of a distribution network, the method being based on an ARIMA model. By establishing an ARIMA model predict a user monthly power outage count; convert a non-smooth element outage count time series to a smooth time series; perform regression on only lagged values of a dependent variable, and on current values and lagged values of a stochastic error term, so as to establish a user monthly power outage count model; according to a prediction result sample an outage point, and at the same time, taking into account a real time load operating state, establish a failure mode effects table based on TLOC criteria and PLOC criteria; and calculate a system recovery time for each instance of device outage, and finally obtain a whole-year reliability index.Type: GrantFiled: June 30, 2016Date of Patent: November 3, 2020Assignee: CHINA ELECTRIC POWER RESEARCH INSTITUTE COMPANY LIMITEDInventors: Wanxing Sheng, Yinglong Diao, Keyan Liu, Xiaoli Meng, Lijuan Hu, Kaiyuan He, Dongli Jia, Xueshun Ye, Weijie Dong, Jiangang Tang
