A display panel includes: a base substrate including a display region and a fan-out region, and the fan-out region is located between the display region and a chip; a plurality of data wires/touch wires located in the fan-out region for respectively electrically connecting a plurality of data lines/touch signal lines with the chip. A portion of the plurality of data wires is located in a first conductive layer while a rest portion thereof is located in the second conductive layer. A portion of the plurality of touch wires is located in at least one of the first conductive layer and the second conductive layer while a rest portion thereof is located in the third conductive layer. A pitch between any two adjacent wires in the first/second/third conductive layer is a first/second/third wire pitch, respectively. The first wire pitch and the second wire pitch are smaller than the third wire pitch.

Display panel and display device

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.

Digital simulation system of power distribution network

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.
