Embodiment approach

[0078] 1. Implementation examples classified according to the type of voltage level of the monitoring point.

[0079] For high-voltage power supply monitoring points with a voltage level of 10kV and above, the voltage measurement is realized through a voltage transformer, and a smart meter with a rated input voltage of AC 100V and a "two-rate" monitoring function for power supply can be selected to realize the "two-rate" monitoring function of power supply. For low-voltage power supply monitoring points of AC 220V / 380V, you can choose a smart meter with a corresponding 220V or 380V rated input voltage and a "two-rate" monitoring function for power supply to realize "two-rate" monitoring of power supply.

[0080] 2. Implementation examples by application.

[0081] The smart meter provided by the present invention has the monitoring function of "two rates" of power supply, according to the actual situation at the site of the monitoring point, and the selection needs of the maste...

Abstract

The invention discloses an intelligent electric meter with a function of detecting power supply reliability and a voltage qualified rate and a detecting method of the intelligent electric meter with the function of detecting the power supply reliability and the voltage qualified rate. The intelligent electric meter comprises a voltage sensor and a current sensor, and the voltage sensor and the current sensor are connected with a sampling circuit through a signal adjusting circuit; the sampling circuit is connected with a digital signal processor (DSP); and MCU is simultaneously connected with the DSP, a data memorizer, a power supply module, a local input/output (I/O) module, a remote communication module and a hardware clock. Alternative current voltage data which are collected by the intelligent electric meter not only are used for electric energy measuring and statistics, but also are used for detection and statistics of the power supply reliability and the voltage qualified rate by conducting classification, timing and accumulation on different ranges where the voltage values locate such as an over upper limit range, a qualified range, a over floor level range, a decompression range, the intelligent electric meter is enabled to possess the function of detecting the power supply reliability and the voltage qualified rate, and applied range of the intelligent electric meter is widened.

Description

technical field [0001] The invention relates to the field of grid power measuring instruments, in particular to an intelligent electric energy meter with monitoring functions of power supply reliability rate and voltage qualification rate and a monitoring method. Background technique [0002] The reliability rate of power supply and the qualified rate of voltage at the receiving end (hereinafter referred to as "two rates of power supply") reflect the important indicators of the power supply service quality of power supply enterprises, and are one of the main contents of the supervision of power supply quality by electric power regulatory agencies. In the vast rural areas, the reliability of power supply and the low qualification rate of voltage are also hot spots for complaints about the quality of power supply services. [0003] There are many factors affecting the reliability of power supply, and the statistical method of power supply reliability is also complicated. The ...
