Energy Estimation on BLDC Electric Vehicle using MATLAB

The need for an efficient electric drive system which has high torque and speed, low maintenance costs is getting increased. However, the motors which are commonly used, such as induction motors and DC motors, have not been able to meet the need. Therefore, a new model with efficiency System and energy consumption using simulated software "MATLAB ® or Simulink®" is made. This model includes battery, power electronics converters, electric motors, and transmission systems. In this case the energy system during regenerative braking breaking is also taken into account. The result of the efficiency value of the batteries, inverter, electric motor and the total efficiency value of the overall system is gathered from the control Brushless Motor (BLDC) models HHDB 350-1000 Watt and some batteries type  SOC with capacity 34-48 Ah used

Induction Heating Process Design Using COMSOL® Multiphysics Software

Induction heating is clean environmental heating process due to a non-contact heating process. There is lots of the induction heating type that be used in the home appliance but it is still new technology in Indonesia. The main interesting area of the induction heating design is the efficiency of the usage of energy and choice of the plate material. COMSOL® Multiphysics Software can be used to simulate and estimate the induction heating process. Therefore, the software can be used to design the induction heating process that will have a optimum efficiency. The properties of the induction heating design were also simulated and analyzed such as effect of inductor’s width, inductor’s distance, and conductive plate material. The result was shown that the good design of induction heating must have a short width and distance inductor and used silicon carbide as material plate with high frequency controller.

The Pricing Transmission Losses in Competitive Electricity Market in Bilateral Contract Market

In power system network, transmission losses is the main factor that must be consider in transportation energy from generator side to load side. In competitive electricity market, the pricing transmission losses must be allocated to the all market participants. This pricing must have economic efficiency on competitive operation of the power systems. Therefore, it is important to provide good methodologies that allow determining a loss allocation among market participants as accurate and fair as possible. In this paper, the transmission loss allocation will be implemented in bilateral contract market using several methods, pro rata, incremental loss allocation, proportional sharing, and unsubsidized marginal allocation

OPTIMAL POWER FLOW: MODELING AND SIMULATION, SOLUTION METHODS, AND ITS APPLICATION USING POWERWORLD SOFTWARE®

Optimal power flow has been used to solve a large class of problems in the power industry, including planning, generation dispatch, and security constrained dispatch. The OPF problem can be described as the cost of minimization of real power generation in an interconnected system where real and reactive power, transformer taps, and phase-shift angles are controllable and a wide range of inequality constraints are imposed. It is a static and a nonlinear optimization problem. In this paper, we will try to see how the OPF is modeled and simulated using powerworld software®, and what solution methods can be used to implement the models. Applications of the optimal power flow methods will also be analyzed based on this software

Rancang Bangun Square Wave Full-Bridge Inverter untuk Pembangkit Listrik Tenaga Angin Mikro

The simple principle of wind power plant is use wind as main exciter to rotate the turbine. The turbine convert wind to electric energy. The output signal is alternating (AC) current. This current was changed to direct current (DC) by rectifier circuit. The DC current was used as charge the energy storage, battery. Next step, the DC current from battery convert to AC current using inverter circuit. The result of inverter shows that the error is 20% with 240V no load
