糖厂自备发电站与“外电”(指国家电力系统的电力网)并网,有许多优越性。但目前尚有相当多的厂,未能并网运行。主要的考虑有下面几点:(1)外电电压波动大,怕影响到厂内生产用电。(2)外电安全率差、线路故障较多,怕并网后影响糖厂安全供电和设备的安全运行。(3)目前外电供应紧张,怕并网后要多用外电。我厂自1963年起就与外电并网运行,十多年来对上面三个问题有所接触并解决了一些问
There are many advantages for the sugar plant-owned power plants to integrate with “external power” (referring to the power grid of the national power system). However, there are still quite a number of factories that have not been able to operate on grid. The main considerations are the following points: (1) Foreign voltage fluctuations, fear of affecting the plant production of electricity. (2) External security rate is poor, more lines failure, afraid of the grid after the safe operation of power plants and equipment security. (3) At present, external power supply is tight, so it is necessary to use more external power after being afraid of being connected to the network. Since 1963, our factory has been connected with the external power grid for more than a decade and has contacted and solved some of the above three problems
