Abstract

The invention provides a two-bus bus-tie type harmonic wave protection method of an office building power distribution cabinet system. According to the two-bus bus-tie type harmonic wave protection method, two harmonic wave protection cabinets are used, and capacitance compensation cabinets and a power distribution cabinet are arranged between the harmonic wave protection cabinets. Each harmonic wave protection cabinet is provided with a main harmonic wave protector, an auxiliary harmonic wave protector and a coordinating module. Each harmonic wave protector is internally provided with a signal collecting circuit and an inverter circuit.

Description

technical field [0001] The invention relates to the field of power distribution, in particular to a harmonic protection method for a two-section busbar bus-connection type office building power distribution cabinet system. Background technique [0002] In the power distribution system, due to the influence of the power distribution cabinet on the power grid, harmonic currents are generated, so it is often necessary to install harmonic protection devices in the power distribution system. These protection devices can modulate and suppress the harmonic currents generated in the power distribution system. However, the arrangement of power distribution systems in some specific fields is not involved in the prior art. Since the layout of power distribution equipment in specific fields is changeable, and the configuration of different equipment in the system changes, it will have a great impact on the harmonic modulation of the entire power distribution system. For example, the p...
