摘要
结合三门峡华阳发电有限责任公司输煤程控系统应用情况,对该系统故障进行了统计分析。分析表明,其主要干扰为外部干扰。对此,从硬件和软件两方面提出了外部设备抗干扰的几种措施。
Combined with application situation of programmable control system for coal handling in Huayang Power-Generation Co Ltd, the various interference factors existing in practical application of programmable control system for coal handling have been analysed. For these, several interference rejection measures for external equipments have been put forward from two aspects, namely hardwares and softwares.
