This study presents a new concept to control a distribution static compensator (DSTATCOM) based on generalised neural network in a three-phase power distribution system. Artificial neural network (ANN)-based controllers play the vital role in the performance improvement of DSTATCOM. However, their application is limited by the increase in complexity as well as the computational time. The proposed...
This paper presents a discrete derivative control technique for dc-link voltage in shunt compensator. It is desired to maintain the dc-link voltage at reference level value for current compensation using Distribution Static Compensator (DSTATCOM) to improve the power quality of distribution systems. The proposed control strategy improves the dynamic performance of DC control loop by taking the values...
Now a days the entire world is considering an escalating demand for electrical energy as a consequence of the hasty population augmentation. The superior penetration of wind energy technology for electrical power production has been growing since past decade due to the unique impressive features of wind technology viz. pollution free, cost effective, low initial cost, less maintenance requirement...
Wind energy conversion system (WECS) technology has been evolved from conventional driven to optimized driven in recent years. For unique features of PMSG like high power density, less maintenance requirement in comparison to the other kind of machine, it is pioneering in the WECS technology. In this paper modeling of PMSG and PWM converter have been explored well. The control of PMSG in its machine...
This paper focuses on the method of load flow study of power bus system using LabVIEW. Here National instruments Software Multisim 12.0 and LabVIEW 2011 are used together to simulate a 4-Bus Power System and using co-simulation of both, parameters of all buses like Voltage, Current, Active and Reactive Power and Power factor has been observed. This approach simplifies the method of study of effect...
Subsynchronous resonance is well known phenomenon in Series compensated transmission line. Flexible AC Transmission System (FACTS) devices can be used to enhance the performance of the transmission line and to mitigate SSR with auxiliary controllers. The use of STATCOM a FACTS device is increasing in the power system for enhancing power transfer capability and dynamic reactive power support in power...
This paper presents two Newton power flow models - the variable shunt susceptance model and the firing-angle model of the static VAR compensator (SVC). Both these models depict the SVC as a variable shunt susceptance. Here, the SVC state variables are combined with the nodal voltage magnitudes and angles of the network for Newton power flow solution. Both these models possess very strong convergence...
