Generating set automatic power generation intelligent controller

Abstract

The invention discloses a generating set automatic power generation intelligent controller, and is characterized in that the intelligent controller includes a main CPU module (1), an auxiliary CPU module (2), a human-computer interaction module (3) and a comprehensive module (4), the main CPU module (1) and the auxiliary CPU module (2) are installed on the comprehensive module (4) by use of pluggable hard connection, the human-computer interaction module (3) is in flexible connection with the comprehensive module (4) through a pluggable flat cable. The intelligent controller provided by the invention improves reliability of a product through modular design and pluggable connection, and realizes integration of eight functions of a set, one generating set only needs to configure one controller to realize full automatic operation of the set, wiring is simplified, and operation reliability is improved; and at the same time, the controller provides an RS485 communication interface circuit, realizes sharing of data on the Internet, and realizes remote monitoring and centralized control of the generating set.

Description

technical field [0001] The present invention relates to the technical field of fully automatic power generation of low-voltage hydroelectric units, specifically a highly integrated generator set suitable for automatic power generation of hydroelectric units with a voltage level of AC400V developed according to the current operating status of hydroelectric units with a voltage level of AC400V Intelligent controller for automatic power generation. Background technique [0002] At present, most domestic hydropower units with a voltage level of AC400V follow the technical scheme of the 1980s. The steering wheel is used for speed regulation of the turbine, and the operator manually rotates the steering wheel to control the opening of the guide vane, thereby controlling the speed of the turbine; The trigger angle is controlled by resistance; the synchronous grid connection is realized by observing the light bulb or manual closing of the electromagnetic mechanical synchronous meter...

Problems solved by technology

In this way, operators are required to be highly concentrated and have a high level of experience; in addition, this solution is all manually operated by operators, so the safety is not high, and the impact on the unit may be greater when it is connected to the grid

In recent years, domestic hydropower units with a voltage level of AC400V have undergone technological transformation one after another. Most of them adopt the scheme of high-voltage units, which can realize the automatic control of the units, but the cost is high; some use excitation control devices, microcomputer protection devices, and control devices. And temperature measurement and other equipment are combined into an integrated screen to realize the automatic control of the unit. The system needs to realize the interface and communication of multiple devices, which increases the complexity of the system, inconvenient operation and maintenance, and high cost
