【摘要】：工厂供配电系统,是指将上级电力系统的输入电压等级降低后，再将电能按需分配到各个工厂厂房或者生产车间的最终用电设备上，使用电设备能够正常运转，从而进行正常的生产活动。一般情况下供配电系统是由总降压变电站、中压配电站、中压配电线路、低压电力室、低压配电线路、现场用电设备等几部分组成。工厂总降压变电站及以下各级配电系统的设计，是根据各个生产车间的负荷容量和性质，工艺流程上的用电负荷分布等各方面因素综合考虑，并在结合国家整体供电情况的大形势下，实现电能安全、可靠、经济的分配。 新型干法水泥生产线的供配电设计就是这样一个典型的例子。本文以新疆伊犁塔斯水泥生产线项目为例，在负荷计算及无功功率补偿，谐波治理，总降变电站方案设计，车间配电站方案设计，短路电流计算及继电保护，电气设备选型（特别是变压器的数量、容量的选择），电缆的选择等几个重要方面对工厂供配电设计展开说明。尤其是谐波治理部分的研究，，将研究结果应用到水泥工程实际当中去，得到了较好的效果。考虑到工业自动化应用的广泛性及重要性，本文对新型干法水泥生产线自动化控制系统也做了一些简介。
[Abstract]:The power supply and distribution system in a factory refers to the reduction of the input voltage level of the superior power system and the distribution of electrical energy on demand to the factory buildings or the final electric equipment in the production workshop, and the electrical equipment can operate normally, thus carrying out normal production activities. In general, the distribution system is a total depressurization substation and medium voltage. Distribution station, medium voltage distribution line, low voltage power station, low voltage power distribution line, field electric equipment and so on. The design of the factory general depressurization substation and the following distribution system are considered according to the load capacity and nature of each production workshop, the distribution of power load distribution in the process flow and so on, and in combination with the country. Under the general situation of overall power supply, we can achieve safe, reliable and economic distribution of electric energy.
The design of power supply and distribution of the new dry cement production line is a typical example. This paper takes the Xinjiang Yili tasse cement production line as an example, in load calculation and reactive power compensation, harmonic control, total reduced substation scheme design, workshop distribution station scheme design, short circuit current calculation and relay protection, electrical equipment selection (special) It is the quantity, the selection of the capacity of the transformer, the selection of the capacity of the cable, the selection of the cable and other important aspects to explain the design of the power supply and distribution in the factory, especially the study of the harmonic control part, and apply the research results to the actual cement engineering, and get the better effect. Considering the wide and important importance of the application of the industrial automation, the new type of drying is taken into account. The automation control system of the cement production line is also introduced briefly.
