要近年來隨著社會對電力需求量的不斷增長，電能緊缺問題日趨嚴重，極大地制約著社會經(jīng)濟的發(fā)展。我國電力工業(yè)的迅速發(fā)展，電能質(zhì)量對于電網(wǎng)的安全經(jīng)濟運行，保證工業(yè)產(chǎn)品質(zhì)量和科學實驗的正常進行以及降低能耗等均有重要意義。為做到節(jié)約電能并合理高效地利用電能，這就需要對電力參數(shù)進行準確、實時地監(jiān)測；此外，對于電力參數(shù)進行高精度、多參數(shù)的測量，又是充分了解電網(wǎng)的運行狀況，尋找并解決電力系統(tǒng)中出現(xiàn)問題的重要途徑。因此，對于電力參數(shù)的測量，尤其是高精度、多參數(shù)、低價格、便攜、穩(wěn)定的實時測量就顯得尤為重要，也一直是人們研究的一個重要的方向。為解決以上問題，本設計選用 ARM7 核的 LPC2124 芯片為測量系統(tǒng)的核心，主要針對我國電力系統(tǒng)供配電的實際情況，通過 ARM7 單片機為核心，配以相應的外圍電路和功能軟件，采用交流采樣技術實現(xiàn)多種電力參數(shù)的在線實時測量和數(shù)據(jù)分析，為電網(wǎng)的安全經(jīng)濟運行提供可靠保證。以提高三相電參數(shù)的測量速度和精度。關鍵字：三相電。交流采樣。實時測量Three phase electric characteristic measurement software designAbstractIn recent years along with the social demand of electric power increasing, energy shortage is being more and more serious, which restricts the development of social rapid development of power industry, power quality for power system safe and economic operation, ensure quality of industrial products and scientific experiment with normal and reduced energy consumption has important significance.In order to achieve energy saving and high efficient use of energy, which is needed for power parameters for accurate, realtime monitoring。 in addition, the electric parameters with high accuracy, multi parameter measurement, and fully understand the operation of power system, find and solve emerging in power system the important way of the , for the measurement of electric power parameters, especially high accuracy, multi parameter, low price, portable, stable and realtime measurement is particularly important, people has always been an important direction in the study.In order to solve the problem above, this design uses ARM7 nuclear LPC2124 chip measurement system for the core, mainly for the power system of our country distribution of the actual situation, through the ARM7 singlechip microputer as the core, with a corresponding peripheral circuit and software, adopting AC sampling technology to achieve a variety of electrical parameter online realtime measurement and data analysis, as the power system safe and economic operation to provide a reliable order to improve the electric parameter measuring speed and accuracy.Keywords: threephase。AC
