This smart wheelchair model can be used by quadriplegic people to move comfortably. Sufferers with paraplegic or leg impairment face issue in achieving locations. A few people try and use a walker in many instances, the patient may also loose balance and fall and injure themselves. To avoid this state of affairs, our model can be used. This version is powered through a raspberry pi; it is geared up with LCD and RF module and atmega controller, Servo motor, a DC motor and a wheelchair. The user just need to touch the displayed options for movement. The transmitter and receiver circuit communicate using RF communication. This version additionally has an emergency characteristic; the person ought to press the alert button in case of emergency. The patient can then circulate the usage of button instructions. The patient can use the forward and backward buttons to move forward or backward, and can press the stop button to stop at a certain point and to make the chair stand, the patient needs to click on stand up button. so that the person sitting on the wheelchair can stand allowing to pick any items without any help.

This paper proposes the hybrid approach for multiple distributed generators placement to achieve a high loss reduction in a primary distribution networks. The analytical method has been extended for practical power injections. This approach is based on improved analytical expressions to calculate the optimum size of DGs and heuristic technique to identify the best locations for DG allocations. The optimal power factors of the DGs have also been evaluated in this work. To validate the proposed hybrid approach, results have been compared with particle swarm optimization (PSO) technique and existing fast improved analytical (IA) approach results. The proposed technique has been tested on 33-bus test system.

The main work focus is on the LCC HVDC reactive power control system with fluid regulated AC voltage. The reactive power and the voltage control capacity of LCC HVDC were examined and demonstrated with controlled condensers. Reactive power control and voltage management have been suggested and associated controllers with variable condensers have been developed on the reverse side of the fuzzy controlled LCC HVDC system. The active corrective side power control is required and a reactive or voltage control has been taken into account in this work. This study looks at the inverter side of the system LCC HVDC with customizable capacitors, reactive power and fluid management of the AC voltage. The usual AC voltage control and PI controller for reactive power is replaced by an injected controller that enhances reaction speed and control. In the MATLAB software with Sim-Power system toolbox, graphs are created using a GUI environment to model the proposed fuzzy-controlled HVDC system.
