Reactive Power Compensation : A Form Of Series Type

In order to optimize the power delivered to the load to increase the efficiency of the secondary circuit, Rs must be diminished to as low of a value as possible. Likewise, in order to optimize the amount of power being delivered to the secondary circuit through coupling, the primary circuit must increase the amount of power from the source, as well as decrease the resistance in the primary coil itself. The quality factor of the secondary coil is inversely related to the secondary resistance, Rs. The system described is shown in Figure

After finishing high school I will be attending St. Clair for their fast track power engineering program learning things like the operation of steam boilers and more depending on how far i go with the tickets, and if I decide to move away or stay close to home. First off in the power engineering field I have to know things from the operation of steam boilers, to refrigeration systems and more. Second there are different classes of power engineering ranging from the fourth class to the first class ticket with different salaries and places to work with each ticket. Lastly if I end up not being able to get a job in power engineering there are other options I could branch into with this course. After finishing high school and attending St. Clair for power engineering all these things need to be taken into account when figuring out where I will finally end up with my career.

A power system is always in a state of disturbance that may lead to instability in the system. The consequences of a major power supply interruption can prove to be so disastrous, that every effort must be made to reduce the impact of such a disturbance. The process of determining the steadiness of the power system following any upset is known as security assessment. In particular, MW security assessment is a process to evaluate the security of the power system following a disturbance. It is done considering the loading conditions in respect of MW power flow on the lines. Each line has a capacity to carry MW power up to transmission line design limits beyond which the lines may trip due to overloading. In this paper MW security assessment has

Basic principle of this type of configuration is isolation of harmonics in between nonlinear load and source. The basic configuration is similar with shunt APF, except that interfacing inductor is replaced by an interfacing transformer, where the injection of harmonic voltage occurs. It is otherwise known as a harmonic isolator, which offers zero impedance to the fundamental and infinite impedance to the harmonic frequency components. Fig. 3.5 demonstrates the basic configuration of a series APF. Series APF is suitable for improving the quality of the distribution source

Abstract— This paper provides an explanation of the various harmonic mitigation techniques available to solve harmonic problems due to inverter operation in three phase power systems. As number of harmonic mitigation techniques are now available including active and passive methods, and the selection of the best-suited technique for a particular case can be a complicated decision-making process. A classification of the various available harmonic mitigation techniques is presented in this paper aimed at presenting a review of harmonic mitigation methods to researchers, designers, and engineers dealing with power distribution systems.

In the industrial sector the various motoring loads are continuously running and generating the inductive load. So the power factor in this system gets reduced due to the inductive reactive power. But the electricity board has a standard limits regarding the power factor values and if the power factor goes below the specified limit; the electricity company charges the penalty to the industrial consumers. The automatic power factor correction panel provides the required compensation to overcome the inductive reactance by using the power capacitors. The microcontroller PIC receives current signal from current transformer and simultaneously gives the signals to the various contactors to connect the capacitors in the line for the compensation. Thus by adding the capacitor to the line will compensate the reactive power and maintains the power factor near to unity. This will avoids the penalty to the industrial consumers and may get the incentives. In the conventional methods we were using the fixed capacitor for compensation. But these were leading to excessive charging of the capacitors causes the voltage surges. Thus it becomes difficult to main power factor near unity by on and off operation of fixed capacitor. The contactor switched capacitors are connected and disconnected automatically eliminating the previous problem.

During paralleling two synchronous generators, some conditions are needed to be fulfilled. Each of the three phases must have exactly the same voltage magnitude and phase angle as the conductor to which it is connected. To achieve this match, the following conditions must be met.

Abstract-Due to the liberalization of the electricity market and the introduction of distributed generation (DG), the importance of distribution loss allocation (LA) has incremented. This paper presents developing method for distribution power LA in radial systems. The proposed method, which based on the results of power flow and considers active and reactive power flows of lines for Loss Allocation (LA) is composed of three steps. In the first step, starting from the source nodes, the puissance loss allocated to all nodes is calculated and then the power loss allocated to the loads connected to each node is obtain. In the next step, the total power loss is allocated to the nodes in order to calculate the power loss allocated to the DGs predicated on the results of this step. In contrast to the precursor step, in this step, allocating

The most frequently used voltages and wiring in the primary distribution system are listed in Table 1. Primary distribution, in low load density areas, is a radial system. This is economical but yields low reliability. In large cities, where the load density is very high, a primary cable network is used. The distribution substations are interconnected by the feeders (lines or cables). Circuit breakers (CBs) are installed at both ends of the feeder for short-circuit protection. The loads are connected directly to the feeders through fuses. The connection is similar to the one-line diagram of the high-voltage network shown in Fig. 1. The high cost of the network limits its application. A more economical and fairly reliable arrangement is the loop connection, when the main feeder is supplied from two independent distribution substations. These stations share the load. The problem with this connection is the circulating current that occurs when the two supply station voltages are different. The loop arrangement

Generation of electrical power in low voltage level is very much cost effective. Hence electrical power is generated in low voltage level. Theoretically, this low voltage level power can be transmitted to the receiving end. But if the voltage level of a power is increased, the current of the power is reduced which causes reduction in ohmic or I2R losses in the system, reduction in cross sectional area of the conductor i.e. reduction in capital cost of the system and it also improves the voltage regulation of the system. Because of these, low level power must be stepped up for efficient electrical power transmission. This is done by step up transformer at the sending side of the power system network. As this high voltage power may not be distributed to the consumers directly, this must be stepped down to the desired level at the receiving end with the help of step down transformer. These are the uses of electrical power
