Description
Technical field
The utility model relates to distributed photovoltaic power generation field, especially relates to a kind of multiuser distributed photovoltaic generation Intelligent remote monitoring system.
Background technology
Along with expanding economy, energy shortage is various countries worldwide all problems faced.Simultaneously as most important available fossil energy material as coal, oil, natural gas etc. are faced with exhausted danger, energy shortage problem is just becoming more and more serious, and has influence on the living standard of people.On the other hand, the problems such as the environmental pollution that fossil energy brings, climate warming cannot have been ignored, have impact on sustainable development, the development of energy-conserving and environment-protective theory and popularization, just more and more receive the concern of people.In numerous novel energies, solar energy have cleanliness without any pollution, safe and reliable, restriction less, the advantage such as inexhaustible not to the utmost, the sustainable use of use, thus there is incomparable advantage.Distributed power generation can electric power on-site elimination, saves power transmission and transformation investment and operating cost, reduces the line loss concentrating transmission of electricity; And to power with bulk power grid and complement one another, reduce net capacity, improve electrical network peak valley performance, improve power supply reliability.
But photovoltaic generation itself has the randomness and intermittent feature that are different from normal power supplies, it is incorporated into the power networks and forms certain threat to the quality of power supply of electrical network and safe and stable operation.On the one hand, the injection of photovoltaic power changes the trend distribution of partial electric grid, has a significant impact, limit mode and the scale of photovoltaic generation connecting system to the quality of voltage of partial electric grid and stability.On the other hand, the motive power controllability of photovoltaic generation is strong, and the limited size whether being in generating state and going out merit is in the performance of weather conditions and photovoltaic system.From the angle of electrical network, the photovoltaic generation be incorporated into the power networks is equivalent to the disturbing source that has randomness, may impact at any time to the reliability service of electrical network.Therefore, the operation of power networks that causes due to the quality of power supply, unsteadiness, island effect etc. of above-mentioned photovoltaic generating system and safety problem greatly will limit China's large-scale promotion of distributed photovoltaic power generation system and application on a small scale.

3, the quality of power supply is had an impact.The material impact of distributed photovoltaic access causes the voltage's distribiuting on feeder line to change, its size affected and access capacity, on-position closely related.Photovoltaic generation generally accesses electrical network by inverter, and frequently turning on and off of this kind of power electronic device, easily produces harmonic pollution.
4, on the impact of relaying protection.The power distribution network of China is mostly single supply radial structure, adopts quick-break, time-limit quick break protection form more, does not possess directivity.Access distributed power source in power distribution network after, its injecting power can make relaying protection range shorter, can not reliably protect overall circuit, even when other parallel branch faults, causes the protective relaying maloperation installing distributed photovoltaic to do.
Due to distributed photovoltaic power generation based on family with, for the problems referred to above, user is difficult to carry out detecting and safeguarding, particularly runs into electric power and goes wrong, as process may cause accident of power supply not in time.In addition, want to keep the high efficiency of distributed photovoltaic power generation will carry out cleaning to power station, small-sized household power station does not have power station detection system, is difficult to safeguard power station in time, affects photovoltaic efficiency yet.More than for topic is problem demanding prompt solution in the distributed photovoltaic power generation process of popularization family.
