After decades of development, photovoltaic power generation have made some achievements. Photovoltaic grid connected power generation system is composed of photovoltaic array, solar charge controller and grid connected inverter. It converts the direct current generated by solar inverter to grid connected inverter and converts it into a power generation system that meets the requirements of grid. Photovoltaic grid connected power generation system can supply power directly into the power grid, but the stability of the power generation process is poor, and it will also have a certain impact on the power grid.

Photovoltaic grid connected power generation and load characteristics
Photovoltaic power generation is greatly affected by the environment, and its power generation will increase with the increase of illumination. Generally, when the sunshine is shining, the power peak is generally at the strongest point of sunshine, which is about 10:00 ~ 14:00. When PV grid connected to large capacity, the load curve will also change. For example, the peak load of a photovoltaic power park appears at about 9:00, while 10:00 ~ 14:00, the equivalent load appears to be small.

PV grid connected power generation and grid planning
With the development of photovoltaic power generation capacity, the load and anti power will show some changes, which makes the original grid to meet the demand hardly, it needs to be replanned in accordance with the actual situation, re scheduling operation mode of power grid, increased the daily workload of relevant personnel to a certain extent, also increased the capital investment.

PV grid connected power generation and scheduling
At present, the photovoltaic power generation is not mature, and the automation function is not perfect, which makes the scheduling situation difficult to change with the voltage and frequency of the power grid. Under the original scheduling, the change of the power grid data will directly lead to the reduction of the dispatching capacity of the power grid, which will make the control and scheduling of power grid more and more difficult.

Photovoltaic grid connected generation and voltage
More and more photovoltaic power is connected to the end and terminal of the feeder line of the power grid, while there is a reverse trend in power grid, which makes the current photovoltaic power generation by the influence of feeder in power grid and will produce pressure drop. The voltage of the substation side is reduced, while the load side voltage is unequal to the side voltage of the substation, which makes the load side voltage there is limit. In addition, according to the relationship of voltage and current, when the current photovoltaic power generation changes, the current is bound to be followed by the change of the power generation and photovoltaic power generation light illumination are closely related, which causes the voltage fluctuation is bigger, may cause power in reactive power regulation for frequent action. effecting adjusting device service life and the safe operation of the power grid.

Photovoltaic grid connected power generation and power grid protection
At present, the middle and low voltage power grid in China is mainly divided into two kinds: the radiation type power supply network and the ungrounded single side power supply. At present, the protection principle of substation mainly includes three kinds: automatic recloser on main feeder, fuse in branch and three stage current protection device on circuit breaker. But the current photovoltaic power generation to large capacity development, so that the grid is no longer a single source radial network into a double end even multiterminal networks caused by the fault current direction, duration and current size change, these changes may cause the circuit breaker tripping, malfunction, resulting in fuse is to lose the original selectivity and protection performance, difficult to guarantee the safe operation of power grid. In addition, the solar grid tie power system itself fault and its anti island protection function, automatic reclosing will also change.

PV grid connected power generation and distributed generation unit
A small amount of distributed generation units have little impact on the power grid, when the distributed generation unit reaches a certain limit, it will cause changes to voltage flicker, harmonics, power loss, power flow, load characteristics and other related components, leading to effect on power grid operation quality, stability and safety.

Under the outdoor working environment, the waterproof protection of telecom power supply is must, but if the product only satisfies the IPX3 (rain) protection level which is not enough, it need to prevent the invasion of rainstorm when it is raining or snowstorm. The waterproof protection only considers the prevention of rainwater, and the prevention of water immersion is not to be considered. In some areas which often occur flood and waterlogging, the platform for outdoor communication stations should be built above 2 meters or other highlands, so that the equipment of telecom stations will not be immersed in water during disasters.

The outdoor cabinet is a closed iron box. When the cabinet is exposed to the summer sunshine, the solar radiation heat will be transmitted into the cabinet through the sun drying surface. The temperature inside the cabinet will rise, which will cause the rectifier module or inverter module of the product and UPS will be shutdown due to over temperature protection. At the same time, the temperature inside the cabinet is too high, which is very unfavorable to the battery. No matter the adsorption type or the colloid sealed lead acid battery will cause the loss of water in the battery medium due to the high temperature. When the battery medium is lack of water, the conversion efficiency of the battery will decrease, and the failure of the battery is not output.

First, the demand for UPS energy saving and environmental protection is increasing. In the situation of international oil price volatility and global energy shortage, material recycling and no pollution to the environment, will become the future development direction of power supply products, with the continuous improvement of the level of information, and in the construction of the data center more emphasis on “green” concept. Especially in the UPS innovation technology and the application of air conditioning in the machine room, more and more modular design is adopted. The modular design of UPS and refrigeration system can avoid energy consumption. By modularized flexible expansion, we can reduce user’s investment in equipment and save energy.

Secondly, the UPS distribution market still occupies the main position. The main body of the distribution market consists mainly of UPS dealers and industry agents, and the UPS dealers here include professional power suppliers and IT channel dealers. According to the distribution of UPS market in China, the share of the distribution market is still more than 50%, which is the main channel for UPS sales. With the rapid development of domestic economy, the serious shortage of electric energy, the further popularization of IT applications, and the rapid rise of public consumer electronics, the demand of customers in the middle and low end market is very large. Although the middle and low end market needs to face relatively dispersed customer groups, the demand for intermediate and low-end industries is not seasonally fluctuated, but relatively stable.

Finally, UPS is becoming more and more domestically made. In the future, the competition environment of domestic UPS market will become more and more standardized and benign. Many manufacturers that fail to guarantee quality and service and will not be guaranteed will be phased out by the market. China UPS brands not only complete the import substitution, but also gradually realize the internationalization.
