(1) hy Huayuan high-voltage generator set is a series of high-voltage generator set produced according to the national standard, [GB2820 general technical conditions for power frequency diesel generating set] and [IEC34-1] national Electrotechnical Commission rotary motor standard. The power fuel of high-voltage generator set can be divided into diesel oil, heavy oil, gas, voltage, etc. It can be divided into 6300V, 10500V and 15000V.
Huayuan high voltage generator has high voltage regulation accuracy, good dynamic performance, small voltage waveform distortion, high efficiency, compact structure, convenient maintenance, reliable work, long service life, good economic performance. Because of its high output voltage, low output current and low power loss during power transmission, it is very suitable for long distance transmission. High-voltage power supply system can be directly connected to high-voltage load, saving a large amount of power supply and distribution system equipment investment is more convenient.
(2) hy high-voltage generator set has been widely used, especially in the application of large capacity requirements and long power transmission distance. high-voltage diesel generator set has obvious advantages such as large capacity, long-distance power supply, high reliability and reasonable structure of supporting distribution system. high-voltage diesel generator set has been used in industry, mining, metallurgy and data. A large number of applications have been carried out in the heart, ports, airports and other fields. The humanized control system saves energy and large investment in power supply and distribution system. The characteristics of high voltage and low current determine the advantages of high voltage generators transmitting at long distance.
(3) HY series high-voltage generating units can supply power to the load by one or more units, or by one or more units, or by parallel grid-connected management system and city grid-connected to form a grid to supply power to the load. The generating units are 6.3KV or 1.05KV diesel power. Crew. N generator line cabinet, generator line cabinet, n generator neutral point cabinet, a bus PT cabinet, a set of automatic parallel control screen (touch screen, automatic parallel, manual synchronization), a set of DC screen, a set of low-voltage power box and other components.
Automatic parallel system, programmable controller is the command core, parallel machine and load distribution of the executor: high-voltage distribution is the distribution unit, and the instrument collects the engine three-phase voltage (by high-voltage PT sampling), bus three-phase voltage (by high-voltage PT sampling), generator three-phase current (by CT sampling). The automatic parallel controller provided in this scheme is a Denmark DEF-GPG all-digital controller. The system can realize automatic start-up, automatic input, automatic parallel, automatic frequency modulation and load regulation, automatic spare redundant control, automatic withdrawal, automatic shutdown, automatic protection and other control functions. It can realize microcomputer monitoring through RS485 interface or RS232.
In order to increase the reliability, it has the function of manual quasi-synchronous parallel operation to realize the manual synchronous parallel generation of n generators. A synchronous meter (with synchronous pulse) is installed in the manual quasi-synchronous parallel car. When the phase angle, voltage amplitude difference and frequency amplitude difference of the parallel car satisfy the parallel connection condition, the synchronous pulse signal is output. When the automatic adjusting device is in effect, the manual accurate adjustment will lock up.
