新型农村配电网数字化、智能化改造分析

为了实现农村高质量建设和高效有序运行,同时改善人民的居住环境,这些需求让农村电力配网需求不断涌现。据农村的规模、户数和用电设备情况,进行详细的电力需求计算。考虑到基本用电负荷、公共设施(如电梯、照明、消防系统等)的电力需求,以及可能存在的高峰用电情况,确保供电系统能够满足整个楼宇的电力需求。该供配电系统工程设计以某新型农村建筑作为研究对象,进行电气系统方案设计,主要设计3个子系统,分别是农村建筑的供配电系统、照明系统和火灾自动报警系统。对于供配电系统的设计,首先分析负荷计算的常用方法,分析鉴定该农村区域的负荷级别,计算所需设备容量。接着依凭经测算得到的设备容量数据,选择导线和电缆的规格以及变压器的容量。凭据负荷的性质,选择供电主接线模式和配电模式。对于火灾自动报警的设计,确定消防的防护级别,选择适合的火灾探测器和联合控制消防形式,绘制火灾自动报警平面图和系统图,其中讨论火情探测报警系统和联合控制消防系统这2个系统。

In order to achieve high-quality construction and efficient and orderly operation of the village,and at the same time improve the people's living environment,these demands have led to a continuous emergence of demand for rural power distribution networks in cities.Detailed power demand calculations are carried out based on the size of the rural area,households and power equipment.Taking into account the basic power load,the power demand of public facilities,such as elevators,lighting,fire protection systems,etc.,and possible peak power consumption conditions,ensure that the power supply system can meet the power demand of the entire building.This power supply and distribution system engineering design takes a new type of rural building as the research object to carry out the electrical system design.It mainly designs three subsystems,which are the power supply and distribution system,lighting system and automatic fire alarm system of rural buildings.For the design of the power supply and distribution system,first analyze the common methods of load calculation,analyze and identify the load level of the rural area,and calculate the required equipment capacity.Then,based on the calculated equipment capacity data,select the specifications of wires and cables and the capacity of the transformer.Select the main power supply wiring mode and distribution mode based on the nature of the load.For the design of automatic fire alarm,determine the level of fire protection,select appropriate fire detectors and joint control fire protection forms,and draw automatic fire alarm plan and system diagram,which discuss the two systems of fire detection and alarm system and joint control fire protection system.
