在民用建筑电力节能控制设计过程中,假设电力控制的稳定性较差,在控制过程中,经常因为各种情况发生断电现象,为防止断电后出现的民用建筑中家用电器烧毁或不能进行电器使用的情况,民用建筑物业都会自备发电机组。本文就一种可编程控制器实现全自动控制的民用建筑中柴油发电机组进行了研究,它可在供电停电时自动投入,保证家用电器供电连续性,也可以与市电并网,进行更大范围的供电应急保障。在应用时,应对发电机主电路及分支线路采取短路、过流、单相接地等重要保护措施,以保证发电机组的可靠运行和民用建筑中家用电器的持续使用。
In the design process of electric energy-saving control of civil buildings, it is assumed that the stability of the power control is poor. In the control process, the power-off phenomenon often occurs in various situations. In order to prevent the household appliances in the civil buildings after the power-off from being burned out or can not be carried out The use of electrical appliances, civil construction properties will bring their own generating units. In this paper, a programmable controller to achieve fully automatic control of civil buildings in the diesel generator set has been studied, it can automatically cut off when the power supply to ensure the continuity of household appliances, electricity can also be with the grid and conduct larger Range of emergency power supply protection. In application, the generator main circuit and branch lines should adopt short circuit, overcurrent, single-phase ground and other important protective measures to ensure the reliable operation of the generator set and the continuous use of household appliances in civil buildings.
