This paper introducesa new expert system (ES) for faulted section determination in electrical power system andinterpretingthe performance of the protective system (relays and circuit breakers). The introducedESrequiresinformation about the power system configuration and about the contacts status (open/closed) of the circuit breakers and protective relays. It can determine the faulted section quickly and accurately for all types of faults including simultaneous faults. It is general, i.e.it can be usedwith any power system,due to the separation between the Facts and Rules. The introducedES isdeveloped and tested by CLIPS environment (C Language Integrated Production System) which uses forward chaining to derive conclusion. The performance of the introduced ES is tested for several power systems, IEEE–6 bustest system, IEEE–9 bustest system andIEEE–14 bustest system, and it shows a distinct performance for all tested systems. But for space limitation, we present in this paper the performance results of the introduced ES for the IEEE–9 bustest system only.

An expert system was developed to consider words' grammar case in Arabic phrases without diacritics. First, the system gets words' morphology and tags using Microsoft tool (ATK), then it depends on Arabic grammar to get words' grammar case in nominal phrases. The system gave a very good results as they compared with Arabic language expert.
This paper presents a new solution that allows the doctors to know drug interactions, considering other affecting factors such as the patient's age, weight, physiological and pathological condition. This solution is characterized by being increment al, not only by enriching the database with drug interactions information, but also by its ability to conclude other interactions through a built-in expert system. The system concludes drugs interactions based on its active substrates and the potential interactions between them or between the drugs families. The system serves in three ways; it determines whether the patient illness is possibly due to the medications he is on. It alerts the doctor to the interaction of the newly prescribed medication with the patient’s medications, and to its influence on the patient’s physiological or pathological condition. Besides, it suggests alternative drugs when needed. The solution offers additional services such as binding between the brand name and the generic drug, and between drugs and diseases.
Today worldwide distributed generation (DG) takes a very important role in the operation of distributed electric power systems. However, the existence of distributed generation may have impacts on different topics, such as fault currents, fault pro tection, coordination schemes or fault location. If there is short-circuit in the system, the presence of one or more distributed generators can affect the fault current levels, the monitoring of voltages and currents at the substation. The main supply generation will not have to inject as much power to the line because of the DG and, therefore, voltages and currents at the substation will be different from the ones that would be measured without DG .
Keeping the voltage within the required limits is one of the key issues of operating a power system. since the voltage in electrical power system is affected significantly by changes of loads and equivalent circuit of the power system, there is a ne ed to regulate the voltage with high control ability. Because of the growing use of FACTS in General and STATCOM among them in power systems to improve voltage stability, and because of the need for software that is not always available, the aim of research is to develop a mathematical model, algorithm and software for load flow analysis at the steady state of power system includes static synchronous compensator STATCOM. The Jacobian matrix in the Newton –Raphson algorithm, which is the relationship between voltage and power mismatches, is extended with the STATCOM variables to adjust the voltage and control of the reactive power witch is injected or absorbed at the point of common coupling, with high controlability. A Complete software has been developed that includes comprehensive control facilities and exhibits very strong convergence characteristics. A Sophisticated algorithm has been verified and the effectiveness of the program is tested by its application to a number of standard power systems including the IEEE 5-bus system, and Syrian transmission network 400 kV.
with different frequency make Voltage Source Converter - HVDC link (VSC-HVDC links) an attractive technology for most power transport in meshed grids. Advantages are the high controllability of active and reactive power at the converter’s terminals and the ability to increase the stability of the surrounding AC system. VSC-HVDC can provide active and reactive control to achieve maximum power transfer, system stability and improve power quality and reliability. This research aims to develop a mathematical model and an algorithm for the analysis of power flow in a steady state of power system containing VSC-HVDC.The Jacobian matrix inNewton- Raphsonalgorithm, which is the relationship between voltage and power mismatches, is extended with the VSC HVDC variablesto control active and reactive powers and voltage magnitude in any combination. A Newton-Raphson load flow program has been developed which includes comprehensive control facilities and exhibits very strong convergence characteristics. Two scenarios have been studied, back-to-back VSC-HVDC link and full VSC-HVDC link connecting two buses in AC networks. The algorithm and the program have been verified through a number of simulation examples carried out on IEEE 14-bus System.
