Control device for voltage of distributed photovoltaic distribution network

摘要

Storage medium with computer executable commands that, when executed by a computer processor, implement a control procedure with the following steps:control of a local control device to control a reactive feed voltage at a photovoltaic inverter locally when the feed voltage rises to a warning value and does not exceed an upper limit;determine whether the blinding power in this area is exhausted after local control of the reactive feed voltage at the photovoltaic inverter and when the feed voltage continues to rise to the upper limit;Require a regional coordinated control of the reactive power supply at an area controller in an area where the local control unit is located, if the blind power in this area is exhausted;coordinated control of the reactive feed voltage at the photovoltaic inverter via the range controller;Require regulation of the take-off of a load voltage control transformer on a power plant control device and control of the load voltage control transformer after exhaustion of all blinding power capacities along the line and if the feed voltage continues to rise to the upper limit;Actively cutting controls of the photovoltaic inverter until the feed voltage does not exceed the upper limit value when the transducer reaches the operating limit and the feed voltage does not exceed the upper limit.
