Background
Wind power generation is a renewable clean energy source, has small environmental pollution and high automation degree, and is increasingly used as a substitute for the traditional fossil energy source in recent years. The system can meet the requirements of users in power utilization areas with rare population and inconvenient arrival of power grids, and has good economic benefit and social benefit.
The installed capacity of wind power is improved year by year, the wind power generation industry develops well, but the problems are increased more and more. Because the timeliness of the whole operation of the wind power plant is very high, a plurality of new energy projects cannot obtain corresponding subsidy electricity prices due to the fact that full-capacity grid connection cannot be achieved, grid connection is delayed, and the requirements of grid rechecking cannot be met in the later period; thereby seriously influencing the degree of the investment income of new energy construction units. Therefore, the wind driven generator needs to be optimally constructed in each stage of installation, debugging, grid connection and operation. And the integral grid-connected power generation of project construction according to the designed time is ensured. The diesel generator is used for carrying out static debugging on the wind turbine generator in advance, so that the whole grid connection time can be greatly shortened, and the construction progress of the whole wind power project is ensured.
After the hoisting of the wind power plant under construction in the early period is finished at present, most of current collecting lines on the periphery of a fan are not completely erected, and the wind power plant is not electrified basically even if the current collecting lines are finished; the main reasons include: 1) hoisting work of the same working surface or an adjacent working surface is not completely finished, large hoisting equipment for hoisting work needs to be avoided, and a sufficient safe clearance airspace is ensured; 2) if the line is powered on, the potential danger of electric shock is brought to personnel in other construction operation areas on the site. Therefore, the practice actually adopted by most of the owners on site is as follows: a vehicle-mounted wheeled 690V alternating-current diesel generator is used for providing an independent power supply, and single debugging is carried out under the condition of no local power grid; meanwhile, the matched voltage stabilizer and the circuit breaker are used as accessories, so that the stability of a power supply is improved, and the safe operation of internal equipment of the debugging fan is protected.
690V vehicle-mounted alternating-current generators on the market at present generally have some problems, and influence the progress and quality of static debugging of a fan; the method specifically comprises the following steps: 1) at present, the static debugging work of a single 2.5MW fan needs 1-2 days, so that a debugging worker at the bottom of the fan needs to connect and remove a phase line and a grounding protection line of a generator every day; 2) after each wiring is finished, the voltage, the frequency and the phase sequence of the generator need to be measured, and the work is repeated and high in danger; 3) most of the wiring terminals are in a nut mounting connection mode, and although the wiring terminals are provided with anti-loosening elastic gasket fastening devices, in the actual use process, the phenomenon that the nuts and the gaskets are loosened due to continuous shaking of a generator body and power failure caused by poor contact points often occurs, so that the safety of voltage stabilizing equipment and fan equipment is influenced.
