摘要
变压器并列运行是提高供电可靠性和解决单台主变过载问题的有效途径,但参数不同的变压器并列会产生环流和负荷分配不均衡等问题。根据变压器并列运行的判别条件,以及参数不同的变压器并列运行时的电压差、环流、循环功率、负荷分配等公式,利用Java语言编制了变压器并列运行计算分析软件。应用该软件可快速校核并列运行条件和输出档位匹配表,有效地解决了参数不同的变压器并列运行时的档位选择问题。
The parallel operation of transformers is an effective way to improve the power supply reliability and solve the overload problem of single main transformer,but the parallel operation of transformers with different parameters will cause problems such as the circulation current and the unbalanced load distribution and so on.Based on the discriminant condition of the parallel operation of transformers and the formulas of voltage difference,circulation current,circulation power and load distribution during the parallel operation of transformers with different parameters,the computation and analysis software of the parallel operation of transformers is programmed by using Java language.The software can be applied to quickly verify the parallel operation conditions and output the matching table of tap positions,which effectively solves the tap position selection problem of the transformers with different parameters during the parallel operation.
