Abstract
The utility model provides an automatic diesel generating set of black start. Relates to a diesel generator, in particular to improvement of a black start mode of the generator. The black-start automatic diesel generator set is low in delay and high in response speed. The starter set comprises a storage battery and a starter, the storage battery drives the starter to operate, the storage battery is electrically connected with the output end of the generator set and charges the storage battery, the output end of the storage battery is disconnected with the starter when the storage battery is charged, and the storage battery drives the starter to rotate when the storage battery is disconnected with the output end. When the generator set normally supplies power, the control coil is electrified, the long closed contact is disconnected, the starter cannot be started, black start can be realized through the long closed contact, complex control logic is not needed, the control mode is simple, and response is fast.
Description
Technical Field
The utility model relates to a diesel generator especially relates to the improvement to the black start mode of generator.
Background
The black start means that after the whole system is stopped due to a fault, the system is completely powered off (isolated small power grids are not excluded to still maintain operation), is in a full black state, does not depend on other network help, and drives a generator set without self-starting capability through the start of the generator set with self-starting capability in the system, so that the recovery range of the system is gradually expanded, and finally the recovery of the whole system is realized. The black start of the power plant and the power station which mainly use fossil fuel in the prior art needs to be controlled by complex logic to finally realize the black start, and the control logic is complex, so the system has high response delay and low reaction speed
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a delay low, the fast black start automatic diesel generating set of response speed.
The utility model discloses a following technical scheme realizes: the utility model provides a black start automatic diesel generating set, includes generating set and starter unit, the starter unit includes battery and starter, the battery drive the starter operation, the battery is connected with generating set's output electricity, gives the battery charges, works as when the battery charges the output of battery with the starter disconnection, works as the battery with when the output disconnection the battery drives the starter rotates.
And a long closed contact is arranged between the output end of the storage battery and the starter and is controlled by a control coil, and the control coil gets electricity from the output end of the generator set.
The power generation device is characterized in that a switching power supply is arranged between the output end of the power generation unit and the control coil, a first output end of the switching power supply outputs 5V direct current, a second output end of the switching power supply outputs 36V direct current, the control coil is connected with the first output end of the switching power supply, a resistor is arranged between the first output end of the switching power supply and the control coil, and the second output end of the switching power supply is electrically connected with the charging end of the storage battery.
Compared with the prior art, the utility model discloses a switching power supply charges for the battery, when the battery stops charging, the normally closed contact is because control coil loses the electricity and resumes initial closed state, and the starter power supply is given to the battery this moment, and the diesel engine of starter normal start drive generating set starts, and control coil gets electric when generating set normal power supply, and long closed contact disconnection, the starter can not start, can realize black start through long closed contact, does not need complicated control logic, and control mode is simple, and the response is fast.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in fig. 1, the black start automatic diesel generator set comprises a generator set and a starter set, wherein the starter set comprises a storage battery and a starter, the storage battery drives the starter to operate, the storage battery is electrically connected with an output end of the generator set and charges the storage battery, the output end of the storage battery is disconnected with the starter when the storage battery is charged, and the storage battery drives the starter to rotate when the storage battery is disconnected with the output end. When the whole power grid is in power failure, the starter is rotated by the storage battery, so that the starter is utilized to drive the diesel engine in the generator set to start and operate normally, the generator of the generator set is driven to generate electricity by the rotation of the diesel engine, the power supply in the power plant is recovered firstly, then, redundant electric energy is input into the power grid, so that the power supply of the whole power grid is recovered step by step, the black start is realized, the black start can be realized by long-closed contacts, the control mode is simple, and the response is fast.
And a long closed contact is arranged between the output end of the storage battery and the starter and is controlled by a control coil, and the control coil gets electricity from the output end of the generator set. The power generation device is characterized in that a switching power supply is arranged between the output end of the power generation unit and the control coil, a first output end of the switching power supply outputs 5V direct current, a second output end of the switching power supply outputs 36V direct current, the control coil is connected with the first output end of the switching power supply, a resistor is arranged between the first output end of the switching power supply and the control coil, and the second output end of the switching power supply is electrically connected with the charging end of the storage battery. The storage battery is charged through the switching power supply, when the storage battery stops charging, the normally closed contact restores to an initial closed state due to power failure of the control coil, the storage battery supplies power to the starter at the moment, the starter is normally started to drive a diesel engine of the generator set to be started, the control coil is powered on when the generator set is normally powered, the long closed contact is disconnected, the starter cannot be started, black starting can be achieved through the long closed contact, complex control logic is not needed, the control mode is simple, and response is fast.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
