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 relia...

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 ...

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 ...

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 abov...

The leakage current is the current flowing into the ground through the earth conductor. In ungrounded situations, if there is a conductive path (such as human body), the current may flow from the surface of the conductive component or the non-conductive part to the ground. An external current is always present in the safety grounding conductor. Usually, the upper limit of the leakage current of medical power is 1/10 of the common power supply. All power leakage current indicators of the IEC601 standard are far more stringent than non  medical power supplies . The technical specifications define several different and critical leakage currents, such as the drain current (along the ground into the ground) and the leakage current of the casing. In the IEC601 standard, the maximum leakage current of the medical power supply of the three main types of equipment is defined differently: Class B: equipment that is not in contact with the patient, such as a laser therapy apparatus. Class ...

Telecom power is the key infrastructure of the entire telecom network, but the proportion of telecom power in the entire telecom industry is not high. Telecom operators purchase in the power supply products is mainly the annual equipment maintenance and system equipment. Among them, the maintenance of power supply equipment usually accounts for a higher proportion of procurement. Telecom operators spend relatively little money on building power systems each year, unless carriers need large-scale upgrades or expansions, operators will increase the amount of power equipment purchases. The  telecom power supply system  is the heart of the telecom system, stable and reliable power supply system, communication system is the key to ensure the safe and reliable operation of telecom system, once the fault caused by the telecom power supply system for telecom equipment interruption, telecom equipment will not run, resulting in economic and social benefits cadmean. Therefore, the tel...
