| Abstract | A remote electrical power monitoring and control system based on LabVIEW is implemented and presented in this thesis. Electrical parameters, such as voltage, current, active power, reactive power, KWH and power factor etc., are measured by a multifunction power meter with MOSBUS protocol. Meanwhile, remotely on-off control of the loads is fulfilled by an 8 channels relay embedded MODBUS protocol. Wireless communication by Zigbee is used to transfer data between the field devices and remote workstation or HMI(human-man interface) device. In case of over-current and under-voltage, lighting alarm is activated in response to the fault conditions. To test the developed system, a simulated power system with a main circuit and three sub- circuits are constructed in a panel equipped with four power meters and an relay module, all built in MODBUS protocol, as well as Zigbee module. The software is developed by G language in the LabVIEW platform due to its easy to seamlessly integrating hardware, many analysis functions for saving time and visualizing data in graphic from. It is demonstrated that the developed system are easy to use, flexible for expanding and less expensive compared to an PLC based power monitoring and control system. |
