Democratic Republic Of Congo Replaces Solar Communication

How can the DRC bridge the digital divide?

Deploying and operating networks, particularly in deep rural areas, continues to be a significant challenge in the DRC. To bridge the digital divide and expand network coverage in underserved communities, the companies have pledged to jointly construct up to 2,000 new solar-powered base stations over six years, using 2G and 4G technologies.

What is mobile internet penetration in the DRC?

Mobile Internet penetration in the DRC is at 32.3% and Orange and Vodacom's announcement to construct new base stations in the country aligns with the country's new vision for the digital economy as included in the National Digital Plan Horizon 2025 adopted in 2019.

Who owns the transmission line in DRC?

The transmission line is owned by DRC's electricity utility, Societe nationale d'electricite (SNEL). The contract for the construction of the converter stations for the transmission line was signed in 1973. The HVDC link faced delays due to civil unrest in the country.

Who owns Vodacom Congo?

Vodacom is majority-owned by Vodafone (65.1% holding), one of the world's largest communications companies by revenue. For almost 22 years, Vodacom Congo has put its technology at the service of the socio-economic development of the DRC, providing a wide range of innovative technological products and services.

Why should you choose Vodacom Congo?

Thanks to its policy of corporate social responsibility, Vodacom Congo gives its subscribers access to solutions that contribute to the social and financial inclusion of the Congolese people. For more than 21 years, Vodacom Congo has been a privileged and constant partner in the economic and social development of the DRC.

How many synchronous condensers does a Kolwezi transformer have?

The Kolwezi transformer also has three 70MVA synchronous condensers connected to the bus bar. The transmission line uses double design air cooled thyristor valves, which are fully insulated to the ground. A combination of six double valves forms a 12 pulse converter unit.

What types of power systems are used in communications infrastructure equipment?

Communications infrastructure equipment employs a variety of power system components. Power factor corrected (PFC) AC/DC power supplies with load sharing and redundancy (N+1) at the front-end feed dense, high efficiency DC/DC modules and point-of-load converters on the back-end.

What is a 3G base station converter?

In a 3G Base Station application, two converters are used to provide the +27V distribution bus voltage during normal conditions and power outages.

What is a multi-output power supply design?

Multiple output designs may also employ a complex regulation scheme which senses multiple outputs to control the feedback loop. Voice-over-Internet-Protocol (VoIP), Digital Subscriber Line (DSL), and Third-generation (3G) base stations all necessitate varying degrees of complexity in power supply design.

What is a preferred power supply architecture for DSL applications?

A preferred power supply architecture for DSL applications is illustrated in Fig. 2. A push-pull converter is used to convert the 48V input voltage to +/-12V and to provide electrical isolation. Synchronous buck converters powered off of the +12V rail generate various low-voltage outputs.

Is a 600 MWp solar plant being built in Congo?

Sun Plus, a unit of The Sandi Group (TSG), has launched construction work on a 600-MWp solar plant in the Democratic Republic of Congo that is part of an even larger project totalling 1 GWp. The two-phase scheme, known as the Kinshasa Solar City, includes the installation of a number of solar photovoltaic (PV) parks near the capital of the country.

What is a giant solar project in DR Congo?

Giant solar project announced in DR Congo The government of the Democratic Republic of Congo has announced plans for a 600 MW solar park for Menkao in the municipality of Maluku, 25km east of the capital, Kinshasa. The project will be the first in a 1 GW series of solar farms around the city, which has a population of ten million.

Which country is planning a 600 MW solar park for Menkao?

The government of the Democratic Republic of Congo has announced plans for a 600 MW solar park for Menkao in the municipality of Maluku, 25km east of the capital, Kinshasa. The project will be the first in a 1 GW series of solar farms around the city, which has a population of ten million.

How much electricity does the Democratic Republic of Congo have?

The Democratic Republic of Congo has a population of 85 million, of whom only around 9% have access to electricity, a figure which falls near 1% in rural areas. The nation has total electric generation capacity of just over 2.67 GW, of which 2.54 GW is hydropower and 135 MW thermal.

What is Kinshasa Solar City?

The two-phase scheme, known as the Kinshasa Solar City, includes the installation of a number of solar photovoltaic (PV) parks near the capital of the country. The 600-MWp phase one was initiated on August 19 and is expected to be completed within a year.

How much does a 1 GW City Solar System cost?

The government has estimated the total cost of the 1 GW city solar network will be around $1 billion. The Democratic Republic of Congo has a population of 85 million, of whom only around 9% have access to electricity, a figure which falls near 1% in rural areas.

What is a hybrid solar/wind based power system?

A hybrid solar/wind based power system comprises PV array, wind turbine, battery bank, controller, inverter, cabling, and other devices (such as fuses etc.). The layout of a BS employing conventional as well as renewable energy sources is shown in Fig. 5.

Do hybrid power systems reduce the cost of isolated power systems?

The hybrid systems comprising conventional and RESs have been shown to significantly decrease the overall cost of the isolated power systems over their total life cycle ( Karki and Billinton, 2001 ).

How to make base station (BS) green and energy efficient?

This paper aims to consolidate the work carried out in making base station (BS) green and energy efficient by integrating renewable energy sources (RES). Clean and green technologies are mandatory for reduction of carbon footprint in future cellular networks.

Can a BS install a solar array or a wind turbine?

However, the foremost challenge in equipping a BS with a solar array or a wind turbine is the sizing and configuration of the systems. Sizing of PV arrays and turbines is directly effected by the fact whether or not a BS is off-grid or on-grid.

Can a battery bank sustain a BS load?

Their energy storage algorithm controlling the battery bank's SoC is shown to sustain the BS load by effectively managing the solar in a stand alone power system.

Can a wind turbine power a BS?

The main challenge is the sizing of the PV panels and the wind turbine to power a particular BS for which feasibility studies have been done using actual site data as well as simulated data, using software like HOMER, that provide the size and configuration of wind turbines and PV panels ( Deshmukh and Deshmukh, 2008 ).
