Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] As shown in Figure 1, the power limiting unit 5, circuit breaker control system 4, integrated control system engineering 16, signal acquisition system 2, and external input and output circuits 3 are integrated into the parallel cabinet as a whole. The parallel control integrated system 16 adopts the WOODWARD EASYGEN 3200 parallel module, which has a high anti-interference overall design and complies with the American Petroleum Institute API standard and the EU EN / CE interference test. The paralleling cabinet is connected to the diesel generator 1, and one end of the circuit breaker control system 4 is connected to the load 17. The voltage and current on one side of the diesel generator 1 and the load 17 are converted into matching voltage and current by the signal acquisition system 2, and then sent to the parallel The detection unit 7 of the vehicle c...

Abstract

The invention discloses a diesel engine generator set digital type joint operating vehicle control device for an oil drilling rig, comprising a joint operating vehicle control integration system 16, a circuit breaker control system 4, a power limit unit 5 and an external input-output circuit 3; the joint operating vehicle control integration system 16 comprises a signal detection unit, a signal data processing unit, a system protection unit, a system alarm unit, a joint operating machine control unit, a voltage and speed regulating output unit, a power distribution unit, an input-output unit, a PID adjustment unit, a logic control unit, and a liquid crystal display screen; and a signal input conductor which is connected with the joint operating vehicle control integration system 16 is used as a shielding line. As the further improvement, the joint operating vehicle control integration system 16 selects a Woodwad easygen 3200 joint operating vehicle module; a voltage isolator is arranged between the Woodwad easygen 3200 joint operating vehicle module and a generator 1; and the power limit unit 5 uses a power transducer. The invention has the advantage that the control device can still operate smoothly, stably and easily under the terrible working conditions of harmonic resistance, interference resistance, and sudden load adding reduction.

Description

technical field [0001] The invention relates to a paralleling control device of a generating set, in particular to a digital paralleling control device of a diesel generator set for an oil drilling rig. Background technique [0002] In recent years, with the improvement of diesel generator automation technology, automatic paralleling and control systems have been promoted and popularized in China. Compared with manual paralleling, automatic paralleling has three advantages: first, it is easy to operate, accurate in action, avoids the impact current that may be generated during manual operation, and improves the safety of system operation; second, it can be controlled according to the size of the load and Changes, automatic input and withdrawal of multiple units one by one, greatly reducing fuel consumption and operating costs, and improving the economy of system operation; third, when multiple units are paralleled, some units are in normal operation (power generation) , oth...
