摘要
研究1/3次分频铁磁谐振的近似解析方法常因涉及过多的繁琐数学推导而使众多技术人员望而生畏。考虑到数字仿真技术的日趋完善和普及,近似解析法的主要目的在于给出定性结果。为此,本文提出一种简化近似解析法,并附有算例。还给出了110kV电压互感器与断路器均压电容所引起的1/3次分频谐振的数字仿真实例。
The excessive and tedious mathematical deduction involved in an approximate analytical methods for 1/3 subharmonic ferroresonance makes many technicians to shrink back.Considering the growing popularity and perfection of numerical simulation technique, the purpose of approximate analysis is mainly pointed to giving qualitative results. Thus, a simplified approximate analytical method is proposed Examples for 1/3 subharmonic resonance caused by the grading capacitors and nonlinear inductance of 110kV electromagnetic voltage transformer and circuit breaker are also presented with numerical simulation results.
