Description
Technical field
The present invention relates to reactive power/voltage control technical field during scale generation of electricity by new energy, in particular it relates to a kind of 330kV wind energy turbine set collects control method of transformer station voltage.
Background technology
After China's wind-powered electricity generation enters the large-scale development stage, produced large-scale new forms of energy base majority is positioned at " three northern areas of China " (northwest, northeast, North China); large-scale new forms of energy base is generally off-site from load center, and its electric power needs to be transported to load center dissolve through long-distance, high voltage.As a example by Gansu Power Grid, by April, 2014, Gansu Power Grid grid connected wind power installed capacity has reached 7,070,000 kilowatts, accounts for the 20.2% of Gansu Power Grid total installed capacity (35,000,000 kilowatts) capacity, becomes the second largest main force power supply being only second to thermoelectricity；Photovoltaic generation installed capacity has reached 4,350,000 kilowatts, accounts for the 12.4% of Gansu Power Grid total installation of generating capacity, and Gansu becomes the province that China's photovoltaic installation is largest simultaneously.At present, Gansu Power Grid wind-powered electricity generation, photovoltaic generation installation account for the 1/3 of Gansu Power Grid total installation of generating capacity.
Due to wind, the intermittence of light resources, randomness and undulatory property, the undulatory property of wind power output can cause large-scale wind electricity field voltage corresponding fluctuation occur.When wind energy turbine set generation voltage relatively large disturbances, if not having enough dynamic reactives to support, wind energy turbine set Voltage Drop will be caused.At present, the low-voltage tolerance of blower fan itself is extremely limited, and now Wind turbines is for the protection of self, often takes the mode automatically excised, causes system to gain merit unbalance, affect system stability；Meanwhile, asynchronous generator, do not possess and maintain and the ability of regulation set end voltage level, the most also will be from Systemic absorption reactive power, therefore voltage stabilization sex chromosome mosaicism is more prominent.
After system voltage falls, if electrical network is not provided that enough idle, Wind turbines set end voltage based on asynchronous generator cannot be rebuild, and causes overspeed protection or the under-voltage protection action excision Wind turbines of all asynchronous Wind turbines in whole wind energy turbine set；If protection cannot be operating normally, owing to the set end voltage of Wind turbines cannot be rebuild, then wind energy turbine set even regional power grid transient voltage unstability can be caused.Owing to influencing each other between voltage and the frequency of the whole electrical network of exchange networked system, Jiuquan region wind power output is widely varied and necessarily causes the voltage of whole system, frequency fluctuation, causes accident to expand further.Three fairly large blower fan off-grid accidents that Gansu Power Grid in 2011 occurs are precisely due to what above-mentioned reason caused.
Summary of the invention
It is an object of the invention to, for the problems referred to above, propose a kind of 330kV wind energy turbine set and collect control method of transformer station voltage, improve electrical network with realization and to the receiving of new forms of energy and send ability, reduce and abandon wind, the advantage improving new forms of energy electricity volume.
