摘要:本文模拟设计一个110kV变电所。开始我们先对系统的线路进行确定了和所有负荷的参数计算，通过对西安110kV变电站及的考虑和对负荷资料分析，满足要求。确定了侧主接线的形式，分别有110kV、35kV、10kV。然后我们对变压器进行选型，计算它的容量和台数。这些全都是根据供电范围确和具体的负荷计算来确定，最后算出各元件的参数，然后进行短路计算主要是在具体的短路的位置，根据最大持续工作电流及其短路电流计算结果，其中包括电压互感器、断路器、过流保护器、隔离开关、母线、电流互感器等，选择并校验电气设备，还需要确定配电装置。接线时需要考虑电力系统和变电站的运行。使用长度方面、多样性方面和经济性也有很大的关系，我们要对电气设备的选择、来设置具体的配电装置、继电保护的方面也很重要，最后的确定有着至关重要的影响。我们充分考虑了环境与经济方面的各个因素，110kV可以选择侧外桥接线、10kV侧应该选择单母线分段接线方式,35kV就用双母线接线。我们为了确定最后的线路、变压器、母线配置和继电保护并进行计算，所以需要根据负荷方面的参数及短路的具体电流来计算。最后对防雷接地及补偿装置进行了阐述，最重要的部分就是对电气主接线图，户内设备的安装，综合柜面部分及其母线，电压互感接线图的绘制。61944

Transformation design of 110KV substation in Xi'an petrochemical plant 2
Abstract:This paper mainly on the transformation of Xi'an 110KV substation and further design. At first we determine the line of the system and all the parameters of the load calculation, through the Xi'an 110KV substation and the consideration and analysis of the load data, to meet the requirements. Determine the main wiring of the form, there are 110KV, 35KV, 10KV. Then we need to determine the main transformer units, capacity, and types of these are all according to the scope of supply accurate and specific load calculation to determine, finally calculated the various components parameters and short circuit calculation is mainly in the position of the specific short, according to the maximum continuous working current and short-circuit current calculation results, including voltage transformer, circuit breaker, over current protector, isolating switch, busbar, current transformer, selection and calibration of electrical equipment, also need to determine the distribution device. Determine the grounding wire and the power system and the operation of the substation itself is closely related. Use of length, perse sex and economy have great relationship. We want to selection of electrical equipment, to set the specific power distribution equipment, relay protection is also very important, finaliZed control mode has very big effect. In terms of science and technology and environmental aspects of the specific contrast, 110KV can choose the side of the bridge wiring, 10KV side can choose a single bus section connection, 35KV can choose to use a double bus wiring. In order to determine the final line, transformer, bus configuration and protection and calculation, so it is necessary to calculate the parameters of the load and the specific short-circuit current. Finally the lightning protection ground and compensation device is discussed in this paper, the most important part of the is the main electrical wiring diagram, indoor equipment installation, integrated counter part and a bus, voltage transformer wiring diagram of the rendering.
Keywords: substation design, integrated counter, the main electrical wiring, short-circuit current calculation of transformer bus selection
