摘要
针对厂矿、企业内投运的2台及以上10kV配电变压器,因用电性质、季节气候引起负荷变化,变压器长时间处于空载和轻载状态,导致损耗增大的问题,提出了2台变压器并列组合优化经济运行自动控制投切方案。在变压器组合已经具备硬件自动控制的基础上,以变压器运行实时负荷参数为控制量,按照预定的经济运行策略进行自动投切,达到就地自动控制和最佳节能的运行方式,节省电能。
For factories and mines, enterprise, those have two or more distribution transformers of lOkV which have been put into operation, as the nature of power customer and seasonal climate cause change in load, that the transformer in a no-load or light-load conditions for a long time, and may result the problem of the loss increases. In order to resolve this problem, a automatic control switching scheme of optimal and economical operation for two parallel combination transformers is proposed in this text. Base on that the transformer combination already have hardware automatic control, use the real-time load parameters of the running transformer as control variable, and according to the Scheduled Economic operation strategy to conduct Automatic switching, So as to achieve the operation mode of local automatic control and best energy-saving ,to save power energy.
