Abstract
A submersible series capacitor compensation device comprises a series capacitor bank, an MOV, a protective spark gap, a damping device and a by-pass circuit breaker; and is characterized in that the open contact of the by-pass circuit breaker is a normally closed node, and the by-pass circuit breaker is connected with a control module to control the on or off of the by-pass circuit breaker. The submersible series capacitor compensation device closes the by-pass circuit breaker for series compensation through the control module under normal mode, so as to use the by-pass of the series capacitor bank as backup; and in case of a line fault, the normal line is used after series compensation in a proper time lag, and after a short-time compensation, the by-pass of the series capacitor bank is used as the backup again. The device solves the problem of subsynchronous resonance.
Description
Technical field
The utility model relates to a kind of compensator with series capaci tance that can be used for high pressure, superhigh pressure, extra-high voltage grid.
Background technology
Existing conventional string is mended and is all moved in system for a long time, so may cause subsynchronous resonance and generator unit shaft system is produced heavy damage, brings potential threat for the safe and stable operation of electric power system.In China especially the Northeast, energy resources and electric load skewness on geographical space, need the electric power in western thermoelectricity base is delivered to load center area, middle part, flow of power is to presenting " transferring electricity from the west to the east, NORTEL south are sent " general layout, and big capacity telecommunicate power transmission mode will become power grid construction and operation normality.Since the passway for transmitting electricity intermediate supports that can access often a little less than, make the transmission system stability limit lower usually, the circuit conveying capacity can not be fully used.In order to promote transmitting capacity of the electric wire netting, improve line efficiency, often need install the higher string of compensativity and mend device.Therefore, a kind of novel string that can fundamentally solve the subsynchronous resonance problem is mended device and is demanded research and development urgently.
The utility model content
The subsynchronous resonance problem that the utility model produces at original string benefit technology, adopt the mode of reverse thinking, research provides a kind of submersible series compensation device, to go here and there in normal mode that to mend bypass standby, after suitable time-delay is mended input with the regular link string, bypass is standby once more after short time interval for compensate for slower at line failure.
For solving the problems of the technologies described above; the utility model provides a kind of latent formula compensator with series capaci tance; comprise: series capacitor bank, MOV, protection spark gap, current limliting damping device, bypass breaker; it is characterized in that: the bypass breaker fracture is normally closed node; bypass breaker connects a control module, is used to control bypass breaker and opens or closes.
To go here and there by control module under the utility model normal mode and mend the bypass breaker closure, make the series capacitor bank bypass standby, after suitable time-delay is mended input with the regular link string, bypass is standby once more after short time interval for compensate for slower, has solved the subsynchronous resonance problem at line failure.
Description of drawings
Accompanying drawing is a structured flowchart of the present utility model.
Embodiment
With reference to accompanying drawing; the utility model comprises series capacitor bank C, metal oxide arrester MOV, protection spark gap, current limliting damping device, bypass breaker; the bypass breaker fracture is normally closed node; bypass breaker connects a control module; being used to control bypass breaker opens or closes; be connected with two isolating switches of connecting with series capacitor bank C, be connected with bypass isolating switch between two series connection isolating switches.
The course of work: under normal mode, will go here and there and mend the bypass breaker closure, the capacitor bypass is standby; When electric power system needs, through of short duration time-delay in 0～0.2 second, open string and mend bypass breaker, series capacitor compensation is put into operation; Treat system works just often in operation after 1～10 second, closed once more bypass breaker, the series capacitor compensation bypass is standby, the submersible series compensation circulation of finishing the work.
