8 1 Overview 1 Overview 1.1 Context In an upgraded 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 difficulty in capacity expansion. To provide competitive site energy solutions, Huawei launches PowerCube series hybrid power supply solutions, including the PowerCube-Solar Hybrid and PowerCube-Grid Hybrid. 1.2 Positioning The PowerCube 1000 is used in the areas with mains absence, low mains quality, and mains unsteadiness, and contains the following systems: Solar hybrid (with ESU-S1300Wh/B) Solar hybrid (with ESU-S1600Wh/B) Grid hybrid (with ESU-F800Wh/A) Grid hybrid (with ESU-F400Wh/A) NOTE Solar hybrid: The solar is the main supply energy. Grid hybrid: The mains is the main supply energy. 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 Cost Reduction The PowerCube 1000 has the following benefits: High compatibility 1

9 1 Overview Standardization 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 communication 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. 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 solar energy storage unit (ESU-S) and fast energy storage unit (ESU-F) Standard element management system, namely, the Network Ecosystem (NetEco) 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 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. Ensures electrical safety and security by using a theft prevention design and alarm generation function for fuel and solar energy. 2

10 2 Functions and Features 2 Functions and Features Table 2-1 describes the PowerCube 1000 functions and features. Table 2-1 PowerCube 1000 functions and features Power system Application Scenario Feature Solar hybrid (with ESU-S1300Wh/B) Solar hybrid (with ESU-S1600Wh/B) Mains absence: The outage duration is 24 hours per day. Average amount of daily sunshine in a year is longer than 3 hours. Fuel can be obtained easily. The system supplies power mainly by converting solar energy and uses the EPM as backup to improve system reliability. The system can be remotely managed in real time and its power consumption can be recorded and analyzed, minimizing the site OPEX. MPPT technology uses fewer PV modules than traditional solar power solutions that use on/off controllers to support the same load power. Using the EPM helps reduce the number of PV modules required and balance the capital expenditure (CAPEX) and OPEX for base stations. Antitheft measures are taken to ensure system security. The automatic EPM optimizes fuel consumption. The EPM can be managed on schedule and be started or stopped remotely. 3

11 2 Functions and Features Power system Application Scenario Feature Grid hybrid (with ESU-F800Wh/A) Grid hybrid (with ESU-F400Wh/A) Mains unsteadiness: The outage duration is 4 to 6 hours per day. Fuel can be obtained easily. Mains unsteadiness: The outage duration is less than 2 hours per day. Mains can be obtained easily. Allows a site to be set up rapidly at low costs, regardless of the climate. Consumes much less fuel than traditional D.G. and battery solutions, reducing the maintenance expense. Allows the mains and EPM to supply power to supply power. Mains+ESU alternate working mode 4

Figure 6-7 shows an ATS-63A1. Figure 6-7 ATS-63A1 Function The ATS is an automatic switch system integrating control modules and power distribution modules. It supports inputs from the two power sources and switches the power inputs from EPM and the mains. The power source can switch to EPM by turning the bypass switch. The ATS has the following functions: 39

47 6 Grid hybrid (with ESU-F800Wh/A) R4850G BC1203 AC power distribution: The ATS provides one AC output, one 10 A AC output, and one maintenance socket output (optional). Bypass: The ATS provides a bypass switch, over which power source can switch to EPM. Real-time managing: The ATS manages the voltage, current, frequency, and power of three-phase outputs. Protection: The ATS is protected against overvoltage, undervolatge. Alarm: open-phase of the D.G. and mains supply. See S4850G1. See BC ESS Components ESU-F800Wh/A Appearance Figure 6-8 shows a ESU-F800Wh/A Figure 6-8 ESU-F800Wh/A Functions An ESU-F applies to an electrical grid with unstable electricity. If the mains is available, an ESU-F allows a high charge current. If the mains is unavailable, an ESU-F supplies power to communications equipment. 40
