In existing self-elevating drilling platform, the platform motor all adopts full manual operation, and the input of generating set will rely on personnel to carry out manually-operated according to the variation of platform load.Therefore the power station not only needs staff on duty, but also is easy to occur the situation of unit overload.In addition, also have problems such as the economy of fuel oil is poor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of drill platform power management system, and this system can change in the past that the platform power station relies on manually operated control mode fully, realizes the automatic management in power station.
A kind of drill platform power management system of the present invention comprises: data acquisition module, central PLC module, first communication module, second communication module, drilling well PLC module and frequency converter module; Data acquisition module links to each other with first communication module by central PLC module, and second communication module links to each other with the frequency converter module by drilling well PLC module; Wherein,
Described data acquisition module is arranged on each generating set lead-in circuit breaker, is used for the parameters such as electric current, voltage of collection in worksite motor operation, and the parameter of gathering is transferred to central PLC module;
Described central PLC module is used for the parameter from data collecting module collected is calculated, and compare with the unit operation limiting parameter of setting, should there be several set grid-connection operations can satisfy the platform burden requirement thereby calculate, and send the control instruction that certain unit was exported or started automatically, stop to drilling well PLC limit module frequency-variable module power;
Described first communication module is used for the control instruction of central PLC module is transferred to second communication module;
Described second communication module is used to receive the control instruction of central PLC module, and control signal is transferred to drilling well PLC module;
Described drilling well PLC module is used for according to the control instruction of second communication module transmission frequency converter module being controlled, when load can not satisfy the actual load needs, drilling well PLC module can temporarily limit the power output of drilling well AC frequency conversion module, start immediately and drop into the operation of next set grid-connection, recover the output of well system power then; When load is reduced to a certain degree, cut off one or several units immediately.
Further, also comprise the panel operation module, this panel operation module links to each other with described central PLC module, is used for setup parameter, and operates whole power management is identical.
The present invention adopts programmable logic controller (PLC) (comprising central PLC and drilling well PLC) and communication module (comprising first communication module and second communication module) to come to realize communication with drilling well AC frequency conversion system (VFD), data acquisition module is according to the real-time current of each generating set that monitors, voltage, power etc. each allow parameter to carry out computing, and give central PLC with the result transmission of computing, send instructions to drilling well PLC by central PLC at last, thereby the output that changes the drilling well frequency converter realizes relying on the variation of load to select the use of being incorporated into the power networks of right quantity generating set automatically.In case load can not satisfy the actual load needs, this system can be temporary transient the power output of restriction drilling well AC frequency conversion system, start immediately and drop into next set grid-connection operation, recover the output of well system power then.When load is reduced to a certain degree, cut off one or several units immediately.The present invention has realized the unmanned engine room function, and the engineer needn't often wait in the cabin and prepare at any time to increase and decrease unit according to the needs of drilling condition, but more time can be gone to check and safeguard other auxiliary equipment.In addition, the automatic management transitions time of power station is short, and is corresponding rapid, saved valuable drilling time.In addition, the present invention has also realized the economy of power station operation, has not only saved fuel oil, and unit is in all the time be operated in optimum state.
Description of drawings
Fig. 1 is a structural representation block diagram of the present invention.
The specific embodiment
As shown in Figure 1, the present invention includes: data acquisition module 1 (5), central PLC module 2, first communication module 3, second communication module 4, drilling well PLC module 5, frequency converter module 6 panel operation modules 7; Data acquisition module 1 links to each other with first communication module 3 by central PLC module 2, and second communication module 4 links to each other with frequency converter module 6 by drilling well PLC module 5.
Data acquisition module 1 is arranged on each generating set lead-in circuit breaker, is used for the parameters such as electric current, voltage of collection in worksite motor operation, and the parameter of gathering is transferred to central PLC module 2.Data acquisition module 1 can be provided with as the case may be, for example is provided with 5.
The PLC of central authorities module 2 is used for the parameter of gathering from data acquisition module 1 is calculated, and compare with the unit operation limiting parameter of setting, should there be several set grid-connection operations can satisfy the platform burden requirement thereby calculate, and send the 5 restriction frequency converter module 6 power outputs of drilling well PLC module or start, stop certain unit instruction automatically.
Drilling well PLC module 5 is used for according to the control instruction of second communication module, 4 transmission frequency converter module 6 being controlled, when load can not satisfy the actual load needs, drilling well PLC module 5 can temporarily limit the power output of drilling well AC frequency conversion system, start immediately and drop into the operation of next set grid-connection, recover the output of well system power then.When load is reduced to a certain degree, cut off one or several units immediately.
The present invention is based on Principle of Communication, adopt programmable logic controller (PLC) (PLC) and have each generator automatic air circuit breaker of communication module, with drilling well AC frequency conversion system (VFD) realization communication.Various operational factors such as the electric current by monitoring each generator, voltage, power, power management system PLC according to result of calculation to each generator breaker and drilling well VFD system output carry out remote control control, realize relying on the variation of load and select the use of being incorporated into the power networks of the generating set of right quantity automatically.This system changes in the past, and the platform power station relies on manually operated mode fully, realize the automatic management in power station: in case the power station load can not satisfy the actual load needs, this system can temporarily limit the power output of drilling well AC frequency conversion system, start immediately and drop into the operation of next set grid-connection, recover the output of well system power then; When load is reduced to a certain degree, cut off one or several units immediately.This system has also realized the unmanned engine room function, and the engineer needn't often wait in the cabin and prepare at any time to increase and decrease unit according to the needs of drilling condition, safeguards other auxiliary equipment but can there be more time to go to check.The automatic management transitions time of power station is short, and response has been saved valuable drilling time rapidly, has also realized the economy of power station operation in addition, saves fuel oil, makes unit always work in optimum state.
