一、概述目前国内的一些电厂(站)的蓄电池组,在运行中对端电池的调整,放电母线电压,大多采用电磁型电压调节器,而端电池的自放电电流,则采用手动调整;或两者都用手动调整。由于电磁型调节器的电磁元件反回系数低,工作点很不稳定,使母线电压质量不够理想。手动调整端电池自动放电电流,不仅增加了运行人员的工作负担,更主要的是端电池的放电电流,随端电池的电压变化而变化的,因而极难作到及时调整,使端电池工况不变,难以延长蓄电池的使用寿命。
I. Overview At present, the battery packs of some domestic power plants (stations) are adjusted manually to adjust the battery voltage of the terminal during operation. Mostly, the electromagnetic voltage regulator is used and the self-discharge current of the terminal battery is adjusted manually. Both are manually adjusted. Due to electromagnetic type regulator electromagnetic component of the low coefficient of return, the working point is very unstable, so that the bus voltage quality is not ideal. Manually adjust the terminal battery automatic discharge current, not only increases the workload of the operating staff, more importantly, the battery discharge current, with the end of the battery voltage changes, which makes it extremely difficult to make timely adjustments to the end of the battery operating conditions The same, it is difficult to extend the battery life.
