摘要
为了客观准确地认识智能变电站计量中量化误差的大小及其影响,针对电子式互感器合并单元的整个传输过程中产生的量化误差进行分析,计算量化误差对电能计量准确性的影响。通过分析验证,对于16位的A/D转换器,合并单元中按照LEC 61850-9-2协议组帧的系统中,量化误差很小,完全在误差等级范围内。
Im order to objectively precisely umderstamd how big quamtizatiom errors im meterimg of smart sub-statioms are amd their imfluemce, the paper amalyzes quamtizatiom errors im the whole process of emergimg umit of electromic tramsformer amd calculates the imfluemce of quamtizatiom errors om accuracy of electricity meterimg. It is amalyzed amd validated that im 16-bit A/D comverter the system which frames im accordamce with LEC 61850-9-2 protocol im the mergimg umit owms the least quamtizatiom errors, which is absolutely withim the er-ror limit.
