Problems solved by technology

[0002] The problem of power quality has received widespread attention worldwide, mainly based on two reasons: the use of modern electrical equipment is becoming the main source of power quality problems, such as power electronic equipment such as rectification and inverter devices and frequency conversion speed control devices A large number of applications, these loads with nonlinear, rich harmonics, impact and unbalanced characteristics will affect the power supply grid, and pose new problems for power quality; on the other hand, users have more and more requirements for power supply reliability High, many precision electronic and power electronic devices are more and more sensitive to power supply quality. These devices are more sensitive to interference from the system than electromechanical equipment, and have higher requirements for power quality. Once power quality problems occur, it may huge economic loss

Abstract

The invention relates to the technical field of power grid simulation, in particular to a power grid nonlinear load simulation system based on LabVIEW. The power grid nonlinear load simulation systembased on LabVIEW comprises an ABC three-phase three-block modulation control end and a harmonic monitoring end which are connected with a PC terminal, the PC terminal comprises a parameter setting module, an operation module and a monitoring module. After the structure is adopted, the purpose of remote monitoring is achieved by acquiring data through the lower acquisition board card, performing FFT operation and transmitting the data to the upper computer in real time through an RS485modbus protocol, meanwhile, board cards are respectively arranged at three phases A, B and C of a power grid for independent control, and harmonic data of each time is adjusted through an upper instruction.
