Description

The multifunctional all photovoltaic power generation apparatus
Technical field
The present invention is mainly concerned with the photovoltaic generation apparatus field, refers in particular to a kind of multifunctional all photovoltaic power generation apparatus.
Background technology
Solar energy as a kind of cleaning, efficiently, never depleted emerging green energy resource, have advantages such as safe and reliable, noiseless, pollution-free, easy maintenance, can be widely used in the every field of social life, particularly be applied in grid-connected photovoltaic system and the power station.
At present, large-scale photovoltaic generating system generally comprises each equipment such as solar photovoltaic assembly array, header box, DC power distribution cabinet, combining inverter, box type transformer and other related communication watch-dog.On the engineering, a plurality of same light photovoltaic assemblies are constituted single channel by cable series connection have photovoltaic group string than the High Level DC Voltage grade; By header box with the big electric current output of Cheng Yilu of confluxing of the little electric current of multichannel photovoltaic group string; Realized the output of many header boxs is entered the distribution output of confluxing by DC power distribution cabinet; The output of DC power distribution cabinet causes combining inverter by cable, exports by the inverter inversion grid connection; Transformer and relevant grid-connection device boost and are incorporated into the power networks the distribution that carries out of the output of inverter; Environment monitor in the electricity generation system, header box, DC power distribution cabinet, combining inverter, transformer etc. are by the communication monitoring of communication monitoring cabinet, and always communicate by letter at the monitoring center with the power station.At present, photovoltaic DC-to-AC converter is indoor type substantially, outdoor type seldom, that the outdoor type photovoltaic DC-to-AC converter is mainly is low power (several hectowatts ~ tens kilowatt), high-power outdoor type inverter does not have the utilization case temporarily.In the large-sized photovoltaic electricity generation system engineering practice, use for satisfying on-the-spot outdoor environment, two kinds of ways are arranged: the one, the scene is built civil engineering class switchgear house specially or is utilized existing building for DC power distribution cabinet, combining inverter, communication monitoring cabinet, settles above-mentioned each discrete cabinet disposed therein; Another kind, equipment supply manufacturer is the inversion room of the special non-civil engineering class of the said equipment manufacturing, above-mentioned each discrete case equipment is pieced together by functional structure be installed on wherein.
In the conventional art, when practice, often be required to be DC power distribution cabinet, combining inverter, related communication watch-dog and attached etc. build switchgear house or adopt high-power room/casing specially, will above-mentioned each discrete cabinet arrangement disposed therein, to satisfy on-the-spot outdoor environment.For example, as existing photovoltaic generating system structure as shown in Figure 1, DC power distribution cabinet, inverter, communication monitoring cabinet and relevant control power supply power supply distribution box are concentrated to settle and are arranged in the mobile room of civil engineering switchgear house or high-power open air.
Relative system, whole DC distribution, inversion generating, communications monitor system do not carry out highly integrated, every function is decentralized in each independent cabinet, the interior external connection of each equipment of system is mixed and disorderly, the inner space utilance is low, system management is not good, and the installation and maintenance inconvenience etc., its concrete manifestation is as follows:
1. when the high power contravariant device used of existing photovoltaic power generation grid-connecting applies to the actual field generating, need other configuring direct current power distribution cabinet, and do not have complete electricity generation system communication monitoring function, electricity generation system needs the configuration communication monitoring cabinet.
