摘要(Abstract)：

变电所所用电电压应满足电能质量对供电电压偏差的要求,所用电电压越限将严重危害变电所的正常运行。以较为典型的3座220 kV变电所内主变压器和所用变压器的配置为例,从电网系统电压、变压器调压装置及额定电压角度对所用电电压影响的因素进行分析,对3台所用变压器每个档位下的电压低值、高值进行核算,详细阐述了如何选取合适的所用变压器档位,并提出了从设计到运行阶段控制所用电电压的策略建议。
The voltage of substation electricity should meet the requirements of the power quality on power supply voltage deviation. The exceeding voltage of substation electricity would seriously jeopardize the normal operation of substation. By taking the configuration of main transformers and transformers for substation use in three typical 220 kV substations for instance, the paper analyzes influential factors of voltage of substation electricity in terms of voltage of power system, voltage regulation device of transformer and rated voltage. The paper calculates low value and high value of each gear on three substation transformers and expounds how to select the proper gear; in addition, it proposes strategy for substation voltage control during design and operation.
