Smarter format change – power pack in the IIoT

With the newAG24, SIKO has expanded its portfolio of posi- tioning drives with intelligent RTE (re- al-time Ethernet). In addition to the tried

ternal components or junction boxes are needed to connect to a higher-level control- ler. This means that the drive is connected only to the supply voltage, and the port for data exchange has to be connected direct- ly to the controller or the next drive in the network. A simpler network connection is hard to imagine. Communication standards In industrial automation it is important that standards be met which make it easier for the system integrator to integrate the pe- ripheral equipment into its control environ- ment.The AG24 serves the leading standard

communication interfaces Profinet, Ether- net IP, Powerlink and Ethercat. Numerous function blocks, add-on instructions, and dif- ferent libraries are important software tools which offer the user a substantial simplifica- tion of system integration. Owing to the extensive experience gained from the applications of the AG25 and AG26 drives, which have already be- come successfully established in the mar- ket, SIKO now also offers a large selection of corresponding software tools for the new AG24.

and tested SIKO positioning drives AG25 and AG26, which are characterised by their ultra-compact design, the AG24 has now been released to expand the portfolio of actuators. Despite the considerable output power and speed of the AG24, all the components are still integrated into one housing. No ex-

“The power industry is facing unprecedented change. By 2025, traditional centralised models will be complemented by a world of distributed energy, disrupting existing business models.” This is the view of Taru Madangombe, Vice President Energy Business Schneider Electric Southern Africa, who will be address- ing delegates at the Sub Saharan Africa Power Summit in Cape Town from 17 to 19 October 2018. His address will include the trends in the energy revolution (4 th Industrial revolution – 4IR) and case studies that indicate how successfully smart grid applications can save money and improve customer satisfaction. “Tomorrow’s grid is integrating a multitude of distributed energy resources (DER), such as distribution generation (DG), storage and flexible loads, and disrupting utility generation through new power grid designs that incorporate national /Interconnections-regional, interme- diate Microgrids (municipal, regional) and prosumers in the mix. A recently installed medium voltage fan application at a steel mill showed a saving of up to 60% with an LSIS-M1000. Featuring an integrated transformer, it is monitored by a standard LSIS PLC, HMI combination with fiber optic communication to the Power Cells. The achieved saving is due to its independently controlled H-bridge cascade Power Cell technology, providing low harmonics and near sinewave output thus elimination the need for additional input and output filters. Thus, when looking to cut the peak tariff charges down to size or getting better power factor correction or just getting The benefits of VSDs Like Soft Starters the VSD’s starting curve is gentle and should nev- er exceeds the maximum motor amps during the start-up. Unlike most soft starters, the VSD generally still takes constant care of itself, the motor and line to prevent failure as far as possible. Additionally, LSIS drives are designed to further improve effi- ciency by injecting just the right amount of energy into the motor to maintaining the necessary speed and torque needed for the ap- plication. The active or passive auto-tuning algorithms built into the LSLV drive range ensure a finely tuned application.

Powering the digital economy

“These unprecedented changes bring increasing complexity and challenges ahead on DER integration, customers that are more active, operational efficiency demands and digital transformation.” According to a McKinsey research report, the world is going to see a 48% increase in electricity demand in 2040, compared to 2020 and a 10 times increase in connected devices. The demand for decarbonised fuels will see 86% of investments in power gen- eration until 2040 be in zero-carbon fuels; of which 71% will be in wind, solar and hydro. Power will become more decentralise, with 12% of generating capacity from DG in 2025 including 65% of DG investments will be distributed to solar PV. “The disruption has started. Our digitised grid operations enable utilities to generate and protect revenue, secure optimal service levels and reduce costs,” concludes Madangombe.
