摘要:
The present invention relates to a method for managing power in electrical installations which: - determines a maximum power reference value (51) and establishes a safety margin for that value for an electrical installation (10, 20, 30, 40, 40), - determines a maximum initial current reference (53) based on the maximum power (51) and on a number of controllable or non-controllable loads or sources connected in the installation for each of the controllable loads or sources connected in the installation, - measures instantaneous consumption and sets (57) its maximum available current reference (54) for each controllable load (3'), - measures power generated and sets its maximum available current reference for each controllable source (7,9), - calculates a total consumption value for the electrical installation using the maximum available current reference for each controllable load or source and compares it with the maximum power (51), - determines whether at least one controllable load or source of the installation is connected to or disconnected from the electric line and determines a new maximum power reference value for the installation.

The invention describes a system and a method for controlling an electric generator connected to the power grid during a voltage drop in the power grid, the system comprising a back-to-back converter (2) connected between the generator (3) and the power grid (4) and also, in parallel to the generator side converter (2a), rectifying means (5) connected in series between the generator (3) and the DC-link (2b) of the back-to-back converter (2), thus providing an alternative way for the energy excess at the generator side to enter the DC-link (2b).
摘要:
The object of the invention is to provide an energy management system for variable resource energy generating systems, which incorporates means for the storing of energy and the management thereof. The system permits the needs which arise in the power grid to be met, and participates in the regulation of the power grid and contributing to the stability and quality thereof.
