SYSTEM FOR REAL TIME CONTROLLING 3-PHASE UNBALANCED REVERSE POWER OF SOLAR POWER GENERATION SYSTEM

摘要

The present invention relates to a three-phase unbalanced reverse power real-time control system of a photovoltaic power generation system. It is possible to balance the load for the solar power generation, the installation cost is low, the implementation is simple and safe, and it is to minimize the loss of solar power generation and increase the energy compensation rate by consuming only the power by the indirect load. In one example, a dummy resistance unit installed on a three-phase power line between the system and the customer load, and variably consuming power according to a power consumption command; And the grid applied power amount (P O ) applied to the customer load in the grid is detected, the solar power generation power amount (P PV ) from the inverter of the photovoltaic system, and the power consumption amount (P R ) from the dummy resistor unit, respectively receiving and detecting, and each amount of power received (P O, P PV, P R) power (P O, P PV, P R) when the base in real-time monitoring, and reverse power generates a reverse power generated or not in the power line a 3-phase unbalanced reverse power real-time control comprising a reverse power management unit that calculates the amount of reverse power based on the calculation, transmits the power consumption command according to the calculated amount of reverse power to the dummy resistor unit, and transmits a solar power generation limit command to the inverter Start the system.
