摘要:

在上个世纪,对电力的需求呈指数级增长。解决当今能源问题的一个途径是减少家庭的能源使用。这就更加强调了对准确和经济的功率测量方法的需求。提供这些数据的目的是优化和降低其功耗。鉴于此,本文重点介绍了利用PIC单片机芯片(PIC16F877A)设计和实现精确可靠的负荷监测系统。这涉及负载的电压、电流和功率因数的精确感测。巧妙地利用微控制器的内置ADC和定时器,降低了系统的设计复杂度。该系统实时连续监测负载,并在LCD模块中显示电压、电流、功率因数、有功功率、无功功率和视在功率等参数。微控制器的使用降低了成本,使装置紧凑。所提出的系统已在实验室中实施和测试单相负载。

英文摘要:

The demand for power has increased exponentially over the last century. One avenue through which today's energy problems can be addressed is through the reduction of energy usage in households. This has increased the emphasis on the need for accurate and economic methods of power measurement. The goal of providing such data is to optimize and reduce their power consumption. In view of this, the present manuscript focuses on the design and implementation of precise and reliable load monitoring system using PIC microcontroller chip (PIC16F877A). This involves an accurate sensing of voltage, current and power factor of the load. A clever utilization of in-built ADC and timers of the microcontroller reduces the design complexity of the system. The proposed system monitors the load continuously on a real time basis and displays the parameters such as voltage, current, power factor, active, reactive and apparent powers in an LCD module. The use of microcontroller reduces the cost and makes the device compact. The proposed system has been implemented and tested in the laboratory for single phase loads.
