Wind hybrid solar inverter system refers to the combination of wind energy and solar energy, and uses the complementary characteristics of two kinds of energy in time to generate electricity and supply the wind energy and solar energy utilization mode. Wind energy and solar energy are renewable and clean energy sources, which are inexhaustible. Therefore, wind solar hybrid power supply system is a new type of green and sustainable generation mode.

Wind solar hybrid power supply system is divided into two types: household type and centralized type according to their power load applications. Household type wind solar hybrid power supply system is suitable for household electricity demand, centralized type wind solar hybrid power supply system is suitable for the user more concentrated in the village, the town and other electricity needs, the number of users is generally a few households to hundreds of households.

The wind solar hybrid power supply system is mainly composed of wind turbine, photovoltaic array, charging controller, storage battery and inverter.

Under the grid connected operation mode, the voltage and frequency of microgrid are all supported by power grid, and each micro source adopts P/Q control mode. The specific control strategy: The working state of the central controller loop to detect the micro source and the load, in the power grid power generation without restrictions, to the maximum output of photovoltaic and wind turbine regulating mode, the energy storage system with electricity hot standby state.

When the micro grid load is less than the micro source of total power generation, photovoltaic and wind turbine power supply spare power to the power grid, when the total generating capacity of micro grid load is larger than the micro source, supplied power from the grid. In the main power grid is limited, determine whether the send power back to the grid, when there is excess electricity to power grid, control the micro source of P and Q, the micro grid to power grid scheduling should not exceed the limit. It can also control the energy storage at peak discharge according to different power price at peak time and valley time, and discharge during valley time, so as to maximize the economic benefit of microgrid operation by using renewable energy.

In the grid operation, there will be some unexpected situations. For example, a blower or PV automatically exit running due to overheating fault, micro controller source to inform the central controller. After the failure has been relieved, then meet the grid conditions, the micro controller sends the grid request information to the central controller, the central controller sends the zero output grid instructions, recalculate the current power generation and power consumption of microgrid, gradually increase the output of the new micro grid source.

In the grid, the load management is simple, when receiving a load out or incorporated into the micro grid, as long as the records, and then recalculate the new power and electricity, according to the need to make appropriate adjustments to the power. The feeder level and substation level micro grid, may also receive the main peak of some scheduling order, this time to the microgrid to assess the situation, to meet the conditions, control of energy storage equipment, charge and discharge in accordance with the time node scheduling.

If the main power overhaul, generally know in advance what time the power cut off, the central controller will control the microgrid in power before the initiative entering the grid operation. If the main fault is detected, the grid voltage or frequency of serious overrun, and outlets of the protection or the controller of quick action, micro grid into passive off grid.

Because the wind in nature is intermittent, the continuity of wind power change greatly, especially in areas where the wind energy resources are not very rich, there is a period of no wind or weak wind. Similarly, the intensity of the sun is also affected by seasonal changes and weather. A single type of wind power supply system or solar power supply system does not have enough wind power or solar energy supply, so its power supply can not guarantee the user’s normal electricity demand. Using wind power generation and solar power generation to form a “wind solar hybrid power supply system” can solve this problem well.

Compared with a single type wind power supply system or a solar power supply system, the wind solar hybrid power supply system has the following characteristics:

1.Wind power and solar energy hybrid power supply system can give full play to complementary advantages of wind and solar energy, make up for the shortage of single type energy, and improve the reliability of power supply system.

2.The wind solar hybrid power supply system according to the situation of the local wind and solar energy resources, reasonably allocate the capacity of wind power and solar power, reducing the system investment demand situation while ensure the users normal use, improve the system performance.

3.The wind solar hybrid power supply system can also optimize the distribution of wind power and solar capacity according to the local wind energy, solar energy resources and the economic conditions of the users, and further improve the reliability of the power supply system.

Safety and isolation are also a major difference between commercial power supply and medical power supply, which is related to safety assurances for medical staff and medical personnel who use the device. Although human skin is considered a good insulator, once very small AC currents are applied to the heart, it can lead to heart muscle fibrillation and neuromuscular damage. Therefore, the patient’s environment, equipment, and any part of the patient may be exposed to the current which must be strictly limited to 40-70Hz.

The level of protection required for medical device applications is related to the proximity of the device to the patient. For the medical system, the insulation and protection indicators have three security levels. First of all, all offline power supplies must meet the basic safety requirements of the EN60950 standard. In addition, medical power supply which close to the patients must be in line with the IEC601-1 standard. In addition to the above 2 requirements, also needs an additional barrier to protect the equpiment. Also, when the mains power goes off, it will take a few seconds or minutes for the backup generator to supply power to the hospital. As a result, many medical power sources and devices that use this power are powered by relays from the medical UPS system. The input waveform of the power supply may change and is no longer ideal sine wave. A medical transformer should be added to the front of the power supply to further improve the security level. The equipment directly used for the patient must meet the highest insulation specifications of all of these parameters.

The telecom power supply is the heart of the telecom system, stable and reliable telecom power supply is the key to ensure the safe and reliable operation of the telecom system. Once the power interruption for telecom equipment interruption caused by the fault of the telecom power supply system, telecom equipments will not run, it will cause paralysis of the telecom systems and the telecom circuit interruption, resulting in economic and social benefits cadmean. Therefore, the telecom power supply system occupies a very important position in the telecom system.

The demand growth of telecom power market is limited, but from a more long-term development trend, telecom power supply in the next 2 years will usher in a small climax.

The clients of telecom power inverter are not limited to telecom operators, as well as telecom equipment manufacturers. Power, whether for telecom operators, or equipment research and development, processing and assembly manufacturing enterprises, can not be ignored. China is a famous manufacturing base in the world, and this has objectively created a strong market pillar for power supply products. These will undoubtedly help the telecom power industry successfully survive the market winter.
