The Design Of Qinhuangdao West 110kV Intelligent Substation

As an important foundation for national development and strong power grid, smart substation main function is to provide reliable support node, the smart devices and the control strategy can achieve interoperability, snapping the shared data in real time and achieving precise control of each link in time, It provides an important guarantee for the safe and reliable operation of the entire smart grid.This article will provide solution on construction of intelligent substation according to QINHUANGDAO west of the original design data; completing the selection of main transformer by running the data calculation; determining the main connection mode by comparing various main wiring forms; performing on the main electrical substation equipment selection on the basis of capacitive current and short circuit current calculation,finally this article determines the QINHUANGDAO west 110 kV substation electrical design scheme.Intelligent QINHUANGDAO west 110 kV substation intelligent design scheme, based on the design of IEC61850 standard, builds “three layer and the two net” structure of intelligent substation, and probes into the network communication mode between design;on the main transformer, high voltage switch and transformer intelligent configuration,designing of the main transformer intelligent monitoring system based on IEC61850 standard for real-time monitoring of transformer; through the analysis of the advantages and disadvantages of different electronic current transformer, it completes transformer for selection and design in bus side and the main transformer location configuration way;optimizing the secondary equipment integration, it designs the secondary equipment of monitoring scheme, improving the automation level and reliability of the power system,finally it gives the west QINHUANGDAO 110 kV substation intelligent implementation plan.
