The powerinterference factors of the DCS system were analyzed and an anti-interferencepower supply scheme was presented for the DCS system.
通过分析dcs系统的电源干扰因素，提出了DCS系统的抗干扰供电方案。

Aiming at actual instance that the frequency of electric network is waving, based on twin-T resistance-capacitance active-trap filter, a trap filter which can filter the powerinterference between 49.
针对电网频率波动的实际情况，基于双t型阻容有源陷波电路，设计了可以滤除频带在49。
