利用零值电压原理及零值电压表在发电并网时的4种指示状态,分析论证了适合小型发电站低压机组并网装置的工作原理,确定了并网的几个重要参数,画出了原理图,介绍了制作调试方法、接线图及并网操作过程。该并网装置取材容易、成本低,适合小型发电站或电力公司生产组装,将小型发电站低压机组手动合闸并网发电改建为自动合闸并网。
Using zero voltage principle and zero voltmeter in power generation and networking of the four kinds of indication state, analyzed and demonstrated suitable for small power plant low voltage unit and the working principle of network devices, to determine the grid and several important parameters, draw the Schematic, introduced the production of debugging methods, wiring diagrams and network operation. The grid-connected device is easy to draw and has low cost and is suitable for the production and assembly of a small power station or a power company. The small-scale low-voltage unit of a small power station is manually closed and the grid-connected power is converted into an automatic grid-connected.
