Program Design for Power Flow Calculation of Power System
Abstract Power flow calculation in power system is a basic and common operation。 In the power system can be very critical analysis, play a key role。 The power flow calculation can be used to analyze the fault problem, and the relay protection device can be adjusted, and the security of the system is analyzed。 Through the calculation can be obtained with the line voltage, amplitude, phase and power and power loss are, and can calculate the running state of complex power system under both normal and fault conditions。 In addition, power flow calculation has become the classic analysis of power systems。 In the research and design of power system planning and operation state of the system, in the comparison of power supply scheme and the system running state of rationality, reliability and economy, need to use power flow calculation。 In the normal operation of the power, the need to analyze the trend, the general situation is to use Newton Ralphson to calculate。
This paper introduces algorithm of power system computer aided the trend analysis method, understand the several power flow calculation algorithm, using Newton method for complex system power flow calculation, through program design can the system operation, each part of the operation state of the whole power system: voltage, power, power loss。 This time mainly uses the MATLAB software to carry on the program design, carries on the simulation design to the system, uses the MATLAB high speed computing power, draws the conclusion, simultaneously carries on the theoretical analysis to the conclusion。 The use of MATLAB language programming to analyze and simulation, it can be very clear that the steady-state characteristics of the system, while verifying the role of MATLAB in power flow calculation。
