Double-redundancy energy management system of deep-sea semi-submersible drilling platform

Abstract

The invention relates to a double-redundancy energy management system of a deep-sea semi-submersible drilling platform. Two generator sets form a power station, and each power station is independently run. Each power station is matched with three slave control stations, and each two power stations are matched with a double-redundancy CPU (Central Processing Unit) control main station. The control main stations are communicated with the slave control stations through CS31 field buses, a human-computer interface is communicated with the CPU of the control main stations through Ethernet, and the CPUs of the control main station are communicated through Ethernet. All Ethernet ports are collected to an Ethernet switch, and finally data is sent to a monitoring alarm system. The energy management and scheduling of the power stations of the deep-sea semi-submersible drilling platform can be realized. The system is modularly designed, the structure is not complex, interfaces are standard and normative, and the cost is increased a bit compared with the previous cost. Compared with the traditional platform energy management system, the reliability of the system can be obviously increased through simple hardware configuration and software change.

Description

technical field [0001] The invention relates to an ocean engineering automation equipment, in particular to a double-redundant energy management system of a deep-sea semi-submersible drilling platform. Background technique [0002] The existing dual-redundant energy management systems of deep-sea semi-submersible drilling platforms mainly have the following disadvantages: [0003] a) The controller has no backup redundancy, and the system reliability is low: the existing platform energy management system is often controlled by a single controller. Once the controller fails, the system will not be able to realize the automatic control function. In some cases, it may cause serious As a result, system reliability is low. [0004] b) The main communication network lacks self-inspection and recovery mechanisms: the existing platform energy management systems often use Ethernet or field bus single-network communication, and have not realized network monitoring and recovery.
