The invention discloses a power quality and loss comprehensive monitoring system of a high power rectification system. The power quality and loss comprehensive monitoring system comprises a voltage regulating rectifier transformer, a rectifier cabinet, a DC load, an inductive filtering device, a data acquisition unit, a serial optical fiber converter, an optical fiber to TCP / IP (Transmission Control Protocol / Internet Protocol) converter and a background PC (Personal Computer), wherein the data acquisition unit comprises a grid side AC voltage and current acquisition unit, a filtering side AC voltage and current acquisition unit, a valve side AC voltage and current acquisition unit and a DC side voltage and current acquisition unit. The monitoring system synchronously measures the voltage and current signals of multiple measuring points at the power grid side, the filtering side, the low-voltage valve side and the DC side in real time, and transmits the acquired data to the background PC through the TCP / IP so as to perform background software processing, thereby realizing the functions of grid side power quality estimation, efficiency analysis on system and each power consumption component and so on, and providing better data and technological supports for green, energy-saving and efficient operation of the high power rectification system.
Description
technical field [0001] The invention relates to a monitoring device for a power system, in particular to a comprehensive monitoring system for power quality and loss of a high-power rectification system. Background technique [0002] The high-power rectification system is mainly composed of key equipment such as rectifier transformers (including phase-shifting and voltage-regulating transformers), rectifier cabinets and filters, which can be divided into 6-pulse and multiple connections (12-pulse, 18-pulse, 24-pulse etc.) structure, there are the following three rectification methods: diode plus saturated reactor uncontrolled rectification, thyristor controlled rectification and thyristor controlled rectification based on inductive filtering technology, which have been widely used in electrolysis, chemical industry and rail transit fields. Multiplex technology through the multiple connection of converters (12-pulse, 18-pulse, 24-pulse, etc.), so that the main content of the ...
