Load distribution control system of domestic combustion driving compressor units

Abstract

The invention belongs to the technical field of gas turbine equipment, and particularly relates to a load distribution control system of domestic combustion driving compressor units. The distributioncontrol system adopts a distributed structure, and comprises a load distribution monitoring human-machine interface HMI, a redundantly configured upper computer management type switch, a network stormresistant redundant three-layer management type switch implemented through a ring network optical fiber, a load distribution controller that adopts a CPU and a communication module of redundant structures, two remote I / O module frames, a guard grating anti-surge and terminal, and a control system used for monitoring a plurality of different combustion driving compressor units, the control systemcomprises a first domestic unit control system, a second domestic unit control system, a third domestic unit control system, a first import RR1 unit control system, a second import RR1 unit control system, a third import RR1 unit control system and a station regulation and control system. The dynamic instability is avoided by the joint control of surge control and load distribution, and the stableoperation of the compressor units is ensured when the process conditions are changed.

Description

Technical field: [0001] The invention belongs to the technical field of gas turbine equipment, and in particular relates to a load distribution control system of a domestic combustion drive compressor unit. Background technique: [0002] In recent years, my country's demand for high-efficiency energy has increased year by year. The country has launched the West-East Gas Transmission Project to adjust the energy structure, driving the rapid development of natural gas-related industries and system engineering. Combustion-driven compressor units are widely used as natural gas supercharging devices in the West-East Gas Pipeline. When the first and second lines of the West-East Gas Pipeline were constructed, my country's gas turbine technology was not yet mature, so the supercharging stations used foreign Rolls-Royce, GE, and Siemens companies. Mature units, in order to solve the monopoly situation of foreign equipment, the country vigorously develops the design and manufacturing ...
