摘要
研究阐述一种新型的可测试电能计量装置的时钟基频误差并采用GPS同步时间校准其实时时钟的系统的研制过程,并对系统的测量不确定度进行了分析与评定。在当前峰谷电价政策下,这种系统为电能计量管理尤其是分时电价的管理提供了一种安全、有效、准确、方便的技术手段,有效地解决了电力行业对计量装置的时钟进行准确测试的重点和难点;当然,该系统也可广泛用于其它计时精确的电子产品的时钟测试。
This article illustrates the development process of a new system, which can measure the clock base frequency and provide GPS synchronous time to calibrate the real-time clock of energy measuring devices. The uncertainty of this test system is analyzed and evaluated. Under current policy of peak-valley tariff, this system provides a safe and effective technical measure for energy measuring administration; this system can also be widely used to test other electronic products that have a precise clock.
