光伏发电系统在水厂中的设计方案探索

Exploring Design Scheme for Photovoltaic Power Systems in Water Treatment Plant

结合某水厂现有供电系统和厂区规划,确定规划分布式光伏装机容量为934.92 kW。考虑厂区负荷情况,采用0.4 kV电压等级并网,以3回线路将分布式光伏系统就近接入厂区配电室低压侧:0.4 kV母线。本项目装机容量934.92 kWp,年平均发电量为930.818 2 MWh。按照发电耗煤平均320 g标煤/kWh进行估算,预计每年可节约标准煤297.9 t。通过上述分析可见,本项目在一定程度上具有节能效益,由此可见,光伏发电系统在水厂的绿色低耗、经济运行方面具有较好的发展前景。

The capacity of Distributed Photovoltaic Power Equipment is determined and planned as 934.92 kW based on the situation of current power system and planning of the water treatment plant.Considering the loading condition of the plant concerned,0.4 kV voltage level grid-connected is adopted and the triple-circuit lines is to be used to connect Distributed Photovoltaic Power and the low voltage side:0.4 kV Busbar of the distribution room nearby.The equipment capacity of this project is 934.92 kWp and the average annual energy output is 930.8182 MWh.297.9 t of standard coal is predicted to be saved yearly based on the calculated average consumption of standard coal by 320 g/kWh.According to the above-mentioned analysis,this project has an energy-saving efficiency to some extent.Therefore,photovoltaic power systems has a good prospect concerning green low-consumption and economic operation.
