This paper investigates the fault detection of a micro parallel plate capacitor subjected to nonlinear electrostatic force. For this end Thau observer, which has good ability in fault detection of nonlinear system has been presented and governing nonlinear dynamic equation of the capacitor has been presented. Upper and lower threshold for fault detection have been obtained. The robustness of th...

Many industrial installations in developing countries start-up as small factories, without regard for the need of compensation reactive power, leading to significant financial losses long term. By improving power factor, customer can reduce its demand and potentially increase efficiency their equipment. A PIC microcontroller is used switch capacitor banks compensate power. In order determine si...

In this paper, the optimal placement and sizing of capacitors for compensation reactive power unbalance in medium voltage distribution networks with unbalanced loads is proposed. The proposed capacitor allocation reduces losses caused by demand unbalance. powers are calculated IEEE STD 1459-2010, presented real values electrical magnitudes three-phase systems. results obtained from method compa...

reactive power management plays an essential role in the secure operation of the power system as an ancillary service. although in electricity markets, the particular attention is paid to active power, the reactive power also plays an important on total generation costs of electricity. on the other hand, as it is mainly confined to local consumption, to avoid market power and maintain the secur...

Powerful subsonic underwater discharges are used as a tool in various industrial applications. The aim of this article is to find the essential design parameters required for pulsed-power system efficiently drive such discharges. Using different capacitor banks and electrode geometries, large number studies were conducted an effort better understand phenomenology discharge. Without developing n...

The proposed photovoltaic Micro Inverter is based on three port flyback with one port dedicated to power decoupling function so the decoupling capacitance is reduced and hence the long lifetime film capacitor is used. One of the two transformers and one capacitor is used for decoupling function. The decoupling capacitor functions as energy storage as well as snubber capacitor to recycle the tra...

for banks and financial institutions, credit risk had been an essential factor that needed to be managed well. credit risk was the possibility that a borrower of counter party would fail to meet its obligations in accordance with agreed terms. credit risk; therefore arise from the bank’s dealings with or lending to corporate, individuals, and other banks or financial institutions.  credit risk...

Abstract With the increasing penetration of photovoltaics (PVs) in distribution networks, PV inverters and capacitor banks (CBs) should be well utilized for volt/var control tackle fluctuations uncertainty introduced by PVs. This paper proposes a multi-time-scale method to coordinate CBs, where complementarity between minute second-level promotes economic secure operations networks. Firstly, mo...

Installation of Shunt Capacitor Banks (SCBs) and Voltage Regulators (VRs) within distribution system is one the most effective solutions in reactive power control for improving voltage profile reducing losses along feeder. However, presence VRs can deteriorate Stability Margin (VSM) feeders. To address this issue, paper proposes a multi-objective programming model simultaneous optimal allocatio...
