Studying the electrical lighting and choosing the kind of lamps is one of the most important factors in the realization of a good lighting. So the extended efforts in lighting art are run to obtain an industrial light very similar to daylight and which can replace it. During studying lighting in any place, we must pay attention to the fact that lighting gives the studied place features according to lighting kind, because good lighting makes the study place more visual.

The harmonics and their effects are considered as some of important modern engineering problems in electrical networks, and mostly its is accompanied with high negative economical reference in the industrial and general electrical networks, so an international universities and companies and research institutes are interested, at this time, for studying it and treating it.

Mathematical modeling is used in different science domains. By using it we can construct several mathematical models. Solving these models, mostly, depend on numerical approximate methods, and especially the case when these models are represented by the system of linear or nonlinear equations. To solve these equations we depend on generation solutions with repeated forms such as Gauss, Gauss. Zaidl, Fixed Point, Newton, and Broyden methods. Beginning from an elementary value, which is a chosen estimation, and on which we depend, we determine the speeding of the convergence and the accusation of the solution which we get by certain accuracy. Problem compute voltages in Aleppo city network nodes to return (to give bake) into solve system linear or nonlinear equations, we obtained these variable in nodes network by considering it to consist of load nodes, control nodes and only one reference node.

Mathematical modelling plays a fundamental role in all science domains. By using it, we can construct mathematical models of several problems. Solving these models, mostly, depends on approximate methods, and when these models are represented by system of linear or nonlinear equations, the most equations have no exact solution .It is necessary to search for approximate solution by using numerical method such as Gauss, Gauss.Zaidl, Fixed Point, Newton, and Broyden methods. Beginning from an elementary value, which is chosen by estimation, and depending upon it to determine the speed of convergence and accuracy of the solution which we get by a certain accuracy.

Protection engineer is concerned with limiting the effects of disturbances in a power system, which if allowed to persist; many damage to plant and interrupt the supply of electric energy. These disturbances are described as three phase and single phase short circuits. In order that a fault study by using computer application can be successfully completed, the selection and application of the protective systems (relays, setting) have been carried out at SWEDIEH POWER PLANT AND SUBSTATION. This corresponds with the abnormal conditions and control circuit breakers so as to isolate the faulty section of that system in order to protect the electrical devices with SPEEDY, SELSCTIVITY, RELIABILITY COORDINATION and minimum interruption to service which is the main objective of this research.
