LC filter is an important part of this hybrid reactive power dynamic compensation. The parameters of capacitor and inductive winding of LC filter change during operation with the changing surrounding temperature, the self-heating and the insulation ageing of capacitor, etc. During the installation and commissioning, there may exist errors that can deviate the actual parameters and correspondent harmonic oscillation frequency from the designed value and result in filter disarrangement.

LC滤波器是动态无功补偿装置中的重要组成部分，由于它的电容器和电感线圈参数，在运行过程中会因周围温度的变化、自身发热和电容器绝缘老化等因素影响而发生变化，在安装和调试过程中会存在误差，从而使实际参数和相应的谐振频率偏离设计值，导致滤波器失谐，这就要求对滤波器进行优化设计。
