South Africa innovates to support soaring renewables growth
South Africa's 2010 Integrated Resource Plan (IRP) targeted 8.4 GW of wind and 8.4 GW solar capacity by 2030 and in 2011 the government launched its Renewable Energy Independent Power Producer Procurement Program (REIPPPP) to accelerate development. The REIPPPP has thus far procured 3.4 GW of wind, 2.4 GW of PV and 400 MW of CSP capacity and has attracted 193 billion rand ($13 billion) of ...

Understanding Static Frequency Converter
Static frequency converter means that's no rotary parts inside it - also called solid state - the definition is relative to rotary frequency converter which is using an electric motor to output adjustable frequency. Static frequency converter is changing fixed grid power through AC to DC to AC by inner electronic parts and components, the multifunctional inverter converts the mains (50 Hertz or ...

Performance comparisons of grid connected SPV system with different MPPT algorithms
This paper presents a performance analysis of grid connected SPV system for different maximum power point tracking (MPPT) algorithms. The detailed mathematical model of grid connected three–phase solar photovoltaic (SPV) system with parametric model of SPV cell, thermal modelling and switching loss calculation of switching devices are discussed. The performance evaluation has been carried out for ...

Change 60Hz to 50Hz Power
In conventional power supplies, the mains is rectified (that means the negative parts of the main cycle are flipped over to become positive). This gives 50 or 60 positive pulses per second. These pulses are used to charge up capacitors that store the charge between top ups. If you put a scope on the capacitor, you will see a sawtooth waveform that shows the top of the pulse, then the voltage ...

A high power factor and low crest factor Cuk converter for lighting systems
This paper deals with the analysis, design and simulation of power factor corrected (PFC), low crest factor (CF) electronic ballast for a compact fluorescent lamp (CFL). The proposed electronic ballast employs a Cuk buck-boost AC-DC converter as a power factor regulator (PFR) operating in discontinuous conduction mode (DCM). In the proposed electronic ballast, a half bridge series resonant ...

Testing population initialisation schemes for differential evolution applied to a nuclear reactor core design
In the process of nuclear core design, reactor cell parameters such as dimensions, enrichment and materials must be adjusted considering restrictions such as the average thermal flux, criticality and sub–moderation. This problem may be formulated using global optimisation methods in order to generate sets of design parameters to be analysed by programs that simulate the neutron interactions in ...

A fast–response sliding–mode controller for quadratic buck converter
The switched–mode power supplies are widely used in very low voltage and high–power applications where large conversion ratios are required. In such cases, the quadratic buck converter is the suitable one compared to buck, cascaded buck and multi–phase choppers, because of their limitations in switching frequency and losses. This paper presents mathematical analysis, design and simulation of a ...

Modelling and measuring the operability of interdependent systems and systems of systems: advances in methods and applications
Interdependency is an important consideration in managing systems and systems of systems. Included in this consideration is identifying, representing, and measuring the ripple effects of dependencies between systems and consumers who rely on their products and services. Anticipating these effects enables planners to minimise dependency risks that, if realised, can have cascading impacts on the ...

Evaluating the effect of resource constraints on resilience of bulk power system with an electric power restoration model
Although reliability standards for electric power systems are well accepted, methods and metrics are not established for evaluating the effects of large–scale disruptions that exceed N − 1 criteria for bulk power systems. This paper introduces a model for simulating restoration of bulk power systems following such disruptions. The model allows analysts to simulate disruption of a bulk power ...

Advances in efficiency optimisation control of electrical servo drive
The development of legislative acts in the world in favour of environmental protection requires the reversion of electrical drives' specifications. Indeed, the efficiency of electrical systems has become a crucial goal in the design of control systems (Farhani et al., 2012). In this perspective, this paper proposes a new control strategy of the association of the asynchronous machine and its ...
