安科瑞交流三相表电表在越南光伏的应用

摘要:本文介绍了PZ96L和AMC96L在越南光伏逆变器上的应用。目前,电网公司通常要求光伏并网系统为不可逆流发电系统,即光伏并网系统所发的电由本地负荷消耗,即自发自用。在并网发电和储能系统中,由于外部环境是不断变化的,为了防止光伏并网系统逆向发电,系统需要进行逆流检测,通过实时监测配电变压器低压出口侧的功率信号来调节系统的发电功率,从而达到光伏并网系统的防逆流功能。

Abstract:This article introduces the application of PZ96L and AMC96L in Vietnam photovoltaic inverters. Right now, grid companies usually require photovoltaic grid-connected systems to be irreversible , that is, the electricity generated by photovoltaic grid-connected systems is consumed by local loads, and excess electricity is not allowed to supply to the grid. The system can regulate power generation in order to prevent the photovoltaic grid-connected system from generating reverse power.
 
1.项目概述 Project overview:
  一家做光伏发电的公司,在确认了我司PZ96L和AMC96L的协议可以跟他们目前使用的太阳能逆变器对接后,选择购买这两款表来作为光伏交流部分的电量统计,来确保不会把光伏产生的电流输送向国网。  
  The photovoltaic power generation company in Vietnam, after confirming that our company’s PZ96L and AMC96L protocols can be connected to their current solar inverters, they chose to purchase these two models as the electricity statistics of the photovoltaic AC part to ensure that the electricity generated by photovoltaic will not be sent to the state grid.
