Description: 三相交流电在国民经济中应用广泛，电路的畅通对工业生产极为重要。由于某种原因造成某相交流电断电，会造成重大的经济损失，因而对线路的检测是十分必要的。单片机三相交流电断相远程报警器，以8051单片机为核心，对三相线路进行不间断检测。当某相线路断电时，不仅可进行近程声光报警，还可进行远程声报警。-Three-phase alternating current widely used in the national economy, the circuit flow of traffic on the industrial production of paramount importance. For some causes of a phase AC power, will cause major economic losses, and thus the line detection is very necessary. SCM-phase long-range three-phase alternating current alarm to 8051 as the core, non-stop for three-phase circuit testing. When a phase power line, not only can be short-range sound and light alarm, sound alarm can also be remote. Platform: |

Description: Power flow studies, commonly known as load flow, form an important part of power system
analysis. They are necessary for planning, economic scheduling and control of an existing system as
well as planning its future expansion. The problem consists of determining the magnitudes and phase
angle of voltages at each bus and active and reactive power flow in each line.
In solving power flow problem, the system is assumed to be operating under balanced
conditions and a single-phase model is used. Four quantities are assumed at each bus. These are voltage magnitude v, phase angle , real power P, and reactive power Q.The Newton Raphson method of load flow analysis is an iterative method which approximates the set of non-linear simultaneous equations to a set of linear simultaneous equations using Taylor’s series expansion and the terms are limited to first order approximation.

Description: 2.1 optimal power flow analysis:
The main aim of Optimal Power flow (OPF) algorithm is to capture a steady state operating point. Generation cost, loss are curtailed by steady state operating point. Further, it also maximizes load ability preserving a suitable system representation in terms of parameters of generators (real and reactive powers, line flow limits, output of various compensating devices etc.) . Usually , classical optimization methods were used but as the technology has advanced and integration of FACTS devices in the power system, the traditional concepts and practices of power systems are placed over by an economic market management. . Therefore, OPF has become complex in nature. So, Artificial Intelligence (AI) methods are used which can solve higher complexity problem than OPF.

Description: In this work we present the ED (economic dispatch) problem in mixed AC-DC (alternative currant- direct current) systems based on the calculation of PF (power flow) and its equivalent losses matrix. The procedure starts by the calculation of the PF for AC-DC system, then the calculation of the losses matrix. After that, we calculate the ED problem by an optimization method called IPM (interior point method). The active powers founded by the ED problem, will be used for the recalculation of the new PF. The process will be repeated until the convergence of the results. At the end several simulations will be set in 14 bus system, contains five production units, with and without DC links.-In this work we present the ED (economic dispatch) problem in mixed AC-DC (alternative currant- direct current) systems based on the calculation of PF (power flow) and its equivalent losses matrix.
