国产DEH装置稳定运行措施探讨

On the Measurements to the Homemade DEH Stable Running

随着单机容量和电网容量的不断增大，火电机组广泛采用DEH（数字电液控制系统，简称电调）做为机组的功频自动调整装置，DEH系统的地位越来越重要。一些国产DEH装置由于种种原因，不能正常投运，直接影响机组的安全稳定运行。本文从分析影响DEH正常投运的因素入手，着重于电子设备的抗干扰能力问题，旨在找出一些提高自动控制装置稳定性的有效措施。

?As the generation unit's and electric net's capacity is increasing, most of generting units have been widely using DEH as turbine's power and fre-quency's automatically controlling equipment and n1aking the role of DEH more and more important.Due to the problems of homemade DEH, generating unit can' t run safely and stably. This article analyies the foctors of interfering with DEH's normally run-ning and puts emphasis on the anti - jamming ability of electric equipment in order to find some effective measurements of improving automatic controlling e-quipments' stability.
