Embodiment 1

[0034] Such as figure 1 As shown, the wind farm control device of the present invention can optimally control the wind farm. The wind farm is located in the oil field area and consists of small and medium-sized wind turbines, and adopts the principle of nearby arrangement. According to area D 1 、D 2 ...,D N Divided into different areas, each area includes wind turbines, oil field loads, and control units. Among them, there are multiple wind turbines and they supply power to the oil field loads in the subregion, forming the first energy flow. figure 1The common bus shown in the figure is connected to the oil field loads of each zone through the grid-connected switch of each zone to form the second energy flow. Each zone has an independent control unit, and the number of control units corresponds to the number of multiple wind turbines. It can monitor the power of the wind turbines and oil field loads in this zone, and perform the first energy flow and / or the second energy f...

Embodiment 2

[0038] Such as figure 1 As shown, the wind farm control method of the present invention is used for zone control of small and medium wind turbines in the oil field area, including the following steps:

[0039] Step 101, setting multiple partitions according to the load demand of the oilfield load. Specifically, according to area D 1 、D 2 ...,D N Divide different areas, each area includes wind turbines, oil field loads and control units, etc.

[0040] In step 102, the field-level controller centrally allocates wind power resources according to the requirement that the wind power capacity is 2 to 3 times the oilfield load, and can select a single or multiple wind turbines according to the power of the wind turbines to achieve multi-variable, that is, X Ni (i=1,2,...m) control. Multi-variable control is to control according to the number of wind turbines, power generation capacity and control parameters of the wind turbines in each zone. The control parameters include but a...

Abstract

The invention discloses a wind power plant control device and a control method, the control device is used for carrying out zone control on small and medium-sized wind turbine generators in an oil field zone, and the control device comprises a plurality of wind turbine generators which supply power to oil field loads in the zone to form a first energy flow; the common bus is connected with the oil field load of each subarea through the grid-connected switch of each subarea to form a second energy flow; and the control units correspond to the multiple wind turbine generators in number and are used for monitoring the power of the wind turbine generators in the partition and the power of the oil field load and switching and selecting the first energy flow and / or the second energy flow. The device further comprises a field-level controller connected with the control unit of each subarea, and the field-level controller can dynamically allocate wind power resources and conduct multivariable control according to the power supply requirement of the oil field load of each subarea. According to the device and the method, the small and medium-sized wind power plants in the oil field area can be subjected to zone control, and efficient and reliable operation of the wind power plants in the oil field area can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a control device and a control method for a wind farm using small and medium-sized wind turbines in an oil field area. Background technique [0002] With the implementation of green enterprise construction, a large number of petrochemical enterprises are also actively pursuing the development concept of low-carbon emission reduction and green environmental protection. Petrochemical enterprises are large power consumers, and the annual power consumption is huge. How to organically combine new energy power generation with the production of petroleum and petrochemical enterprises, efficiently promote the utilization of renewable energy, and ensure the safety of electricity use in petroleum and petrochemical enterprises has become an important aspect of the organic combination of traditional energy and new energy. [0003] The single unit capacity of commercial large-c...
