Global technology company in power and automation, ABB, has recently delivered electric balance of plant for an 86MWp project near Prieska in South Africa.

This packaged inverter solution comprises locally manufactured inverter stations and medium voltage (MV) stations with related services.

The project has been developed by Mulilo Sonnedix and is to be built by Juwi ZA. The site is located in the Northern Cape region of South Africa close to Prieska, and forms part of the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) round 3 projects.

The nominal rating of the project is 76MW AC—the plant is feeding the generated power to the national high voltage grid. The deliveries started in October 2015, and are supporting the rapid connection target to the distribution network by May 2016.

Inverter technology

[quote]The global power solutions company’s scope of delivery includes forty 2MW PVS800-IS inverter stations, each containing two PVS800 central inverters, and respective MV stations with 2,4 MVA transformers and ring main units (RMU). ABB PVS800 central inverters and inverter stations are manufactured in ABB’s Johannesburg facilities as well as the 22 kV Ring Main Units (RMUs).

Together with locally manufactured medium voltage transformers, the local content of ABB’s delivery exceeds 60%. The hardware delivery is supplemented by a service offering that includes training and commissioning and local support for the years to come.

Silviu Martinescu, Manager of ABB’s business unit Power Conversion in South Africa said: “…the high local content that ABB is able to provide, offer customers a real, bankable solution that we are able to support for years to come in South Africa.”

According to Martinescu: “Based on the latest estimates, just in South Africa, an impressive 1,041GW of PV capacity are expected to be installed within a three-year period through 2018.”

Meeting energy and financial needs

The PVS800-IS inverter station, rated from 1,75 to 2MW, is designed for multi-megawatt PV power plants. The inverter station uses two 875kW or 1,000kW PVS800 central inverters.

Depending on the size of the PV power plant, several inverter stations can be combined to meet the needed capacity. With a wide list of approvals and with advanced and flexible grid support functions, the inverter station meets all the applicable network connection requirements, regardless of where the project is located.

To help meet bankability requirements and secure the highest return on investment, ABB supports its customers with a dedicated global service network providing a complete range of life cycle services in more than 60 countries.
