8 1 Overview 1 Overview 1.1 Context In an upgraded indoor or shared site with traditional diesel generators, customers face many problems such as great fuel consumption caused by long D.G. operating duration, frequent D.G. maintenance, fuel thefts, no remote energy management and monitoring, and difficulty in capacity expansion. To provide competitive site energy solutions, Huawei launches PowerCube series hybrid power supply solutions, including the PowerCube-Diesel Hybrid, PowerCube-Solar Hybrid, and PowerCube-Grid Hybrid. In addition, Huawei evolves PowerCube 1000 V300R002C00 into PowerCube 1000 V300R002C Positioning The PowerCube 1000 is used in the areas with mains absence, low mains quality, and mains unsteadiness, and contains the following systems: Indoor hybrid power system Outdoor hybrid power system Co-site hybrid power system Indoor temperature control unit (TCU) NOTE Mains absence: The outage duration is 24 hours per day. Mains unsteadiness: The outage duration is less than 12 hours per day. Low mains quality: The outage duration is greater than 12 hours per day. 1.3 Benefits The PowerCube 1000 has the following benefits: 1

9 1 Overview Cost Reduction Standardization High compatibility Maximizes the reuse of current devices, including the alternating current transfer switch (ATS), D.G., energy storage system (ESS), and power supply unit (PSU), without reducing the capital expenditure (CAPEX) for customers and interrupting the power supply to communications equipment. Flexible design of energy storage space The flexible design of energy storage space applies to various upgraded indoor sites and decreases the number of outdoor cabinets. Various temperature control upgrading solutions The EcoCool, split-type DC variable frequency air conditioner, and reused AC air conditioner help to effectively reduce the D.G. operating duration and fuel consumption. Intelligent power combination The D.G. and storage batteries can be combined. Compared with the D.G.+D.G. solution, this mode reduces the fuel consumption average by 50%. The Solar Power System can be combined with the mains, D.G., or storage batteries. Compared with the Solar Power System, this mode reduces the CAPEX by 10% to 30%. The mains can be combined with the Solar Power System, D.G., or storage batteries. This mode requires less or even no fuel than the mains+d.g. solution, because the D.G. is not required if the main is normal. Direct current (DC) power supplies are accepted. Standard platform Controller platforms such as the energy control center (ECC) and solar supply unit (SSU) Energy storage platforms such as the deep cycle battery (DCB-A) and solar cycle battery (SCB) Standard element management system, namely, the Network Ecosystem (NetEco) (Note: HTTP is not a secure protocol) Flexible combination Intelligent Management The total cost of ownership (TCO) is minimized by combining the D.G., mains, Solar Power System, and storage batteries flexibly. The D.G., Solar Power System, or mains can be used as the active power source based on site requirements. Power 1000 V200R003 with DCB-As and SCBs are smoothly upgraded to PowerCube1000 V300R002. Electricity calculation In a co-site environment, a power system supplies power for the devices of various operators. Calculating the electricity of different devices provides extra customer values. Power network management Uses the NetEco to recognize energy equipment, collects data about energy equipment, and creates lists on which equipment and data are displayed. Records equipment running information and prompts for routine maintenance. 2
