General Description
一般说明

The proposed Solar PV Power Plant is planned to have a peak capacity of approximately 250 MW, consisting of 602,420 Solar PV modules, 1,200 solar inverter units, 40 smart transformer stations, and a 220/33 kV Substation. The substation at the solar PV power plant will connect to the national grid through a 12 km, 220 kV single-circuit transmission line that links to the 220/66 kV Zesco Substation.
拟建的太阳能光伏电站计划峰值发电能力约为 250 兆瓦，由 602 420 个太阳能光伏组件、1 200 个太阳能逆变器单元、40 个智能变电站和一个 220/33 千伏变电站组成。太阳能光伏发电厂的变电站将通过一条 12 千米长的 220 千伏单回路输电线路与国家电网相连，该线路与 220/66 千伏 Zesco 变电站相连。

The transmission line will utilize a double 225 mm² ACSR (2xLion) conductor set, which will be strung on standard CEC 220 kV structures.
输电线路将采用双 225 mm² ACSR（2xLion）导线组，并将在标准的 CEC 220 千伏结构上串联。

Plant Layout
工厂布局

The proposed power plant will feature approximately 602,420 polycrystalline Solar PV modules, covering an area of about 250 hectares. Each module is expected to have a nominal output capacity of 415 W at 39.3V. In the setup, 28 of these Solar PV modules will be connected in a string, and 18 strings will be connected in parallel to a single inverter. The modules will be mounted on a fixed ground mounting system with two vertical module rows in a portrait configuration on each structure.
拟建电站将采用约 602,420 块多晶硅太阳能光伏组件，占地约 250 公顷。每个模块在 39.3V 电压下的额定输出功率预计为 415 W。在安装过程中，28 个太阳能光伏组件将连接成一个组串，18 个组串将并联到一个逆变器上。模块将安装在一个固定的地面安装系统上，每个结构上有两个纵向模块行。

The preferred inverter for this project is the decentralized SUN2000-185KTL-H1 Smart String Inverter by Huawei Technologies, with approximately 1,200 inverters required. The output from these inverters will be connected to a 0.8 kV busbar in a containerized Smart MV transformer. The generated power at 0.8 kV will be stepped up to 33 kV via a 6.3 MVA transformer, connected to a 33 kV bus at the project site. The Huawei STS-6000K Smart Transformer Station is recommended for this purpose.
该项目的首选逆变器是华为技术公司的分散式 SUN2000-185KTL-H1 智能组串逆变器，大约需要 1,200 台逆变器。这些逆变器的输出将连接到集装箱式智能中压变压器中的 0.8 千伏母线上。0.8 千伏的发电功率将通过一台 6.3 MVA 变压器升压至 33 千伏，并连接至项目现场的 33 千伏母线。为此，推荐使用华为 STS-6000K 智能变电站。

The 33 kV bus will then be connected to a 220 kV busbar at the project site through four 60 MVA power transformers. This 220 kV busbar will subsequently connect to the 220 kV busbar at the Zesco Substations via a 12 km single-circuit 220 kV transmission line.
然后，33 千伏母线将通过四台 60 兆伏安电力变压器连接到项目现场的 220 千伏母线。这条 220 千伏母线随后将通过一条 12 千米长的 220 千伏单回路输电线路与 Zesco 变电站的 220 千伏母线相连。

The energy generated by the plant will be fed into the national grid through the existing 220 kV Zesco Substations. A 220/33 kV substation located at the project site will connect the power plant to the Wells Spring and Siavonga (Lusitu) Substations via a 12 km, 220 kV transmission line. This transmission line will utilize double 225 mm² ACSR (2xLion) conductors, which will be strung on standard CEC 220 kV structures. The geographic representation of this setup is shown in Ex Fig 3 below.
发电厂产生的电能将通过现有的 220 千伏 Zesco 变电站输入国家电网。位于项目所在地的 220/33 千伏变电站将通过一条 12 千米长的 220 千伏输电线路将发电厂与 Wells Spring 和 Siavonga（Lusitu）变电站连接起来。该输电线路将使用双 225 mm² ACSR（2xLion）导线，并将在标准的 CEC 220 千伏结构上进行串联。该设置的地理示意图如下图 3 所示。

Project Cost and Economic Analysis
项目成本和经济分析

Project Cost
项目成本

The implementation of the 250 MWp GTL Solar PV Power Plant is projected to cost USD 220 million, which translates to a unit cost of USD 0.88 million per MWp. The project is deemed economically viable if the tariffs exceed 8.5 US¢/kWh, as the Net Present Value (NPV), Benefit-Cost (B/C) ratio, and Economic Internal Rate of Return (EIRR) are positive within the considered range of discount rates. The cost estimate is detailed in Ex Table 5 below.
GTL 250 MWp 太阳能光伏电站的实施预计耗资 2.2 亿美元，单位成本为每 MWp 0.88 万美元。如果电价超过 8.5 美分/千瓦时， 在考虑的贴现率范围内，净现值 (NPV)、效益成本 (B/C) 比率和经济内部收益率 (EIRR) 均为正值，则该项目被视为经济上可行。成本估算详见下表 5。
