Abstract

The invention provides a control system and method of a hydraulic type CNG filling substation. A control system of the hydraulic type CNG filling substation comprises a hydraulic type long pipe semitrailer and a hydraulic substation pressurizing pry. A gas convergence main pipe on the semitrailer leads up to the back portion of the semitrailer from the front portion of the semitrailer and is connected to a CNG rapid connector and connected with a gas pipeline of the hydraulic substation pressurizing pry. According to the control system and method of the hydraulic type CNG filling substation, through the pipeline system of the filling substation and the CNG semitrailer, automatic control over the full operation process of the hydraulic substation can be achieved, and manual intervention isnot needed; the remaining amount and pressure of CNG in each steel cylinder can be monitored in real time, on the premise of guaranteeing normal operation of the filling substation system, pressure supplementation operation can be automatically conducted on CNG in a steel cylinder without liquid infusion, the pressure fluctuation problem in the gas filling process is solved, especially, the gas filling interruption phenomenon existing in the steel cylinder group switching operation process can be avoided, and the problem that in the prior art, manual operation is needed to balance pressure isavoided; and since automatic continuous operation is conducted, frequent start of a motor is avoided, and the operation energy consumption is lowered.

Description

technical field [0001] The invention belongs to the technical field of a hydraulic CNG (Compressed Natural Gas) filling substation system, and relates to a hydraulic filling substation control system and a control method. Background technique [0002] As a clean energy, natural gas has been widely used all over the world. Among them, using natural gas as fuel to drive vehicles and other equipment has become a very important aspect in the field of natural gas utilization; in order to facilitate transportation and loading and improve its efficiency, it is usually necessary to pressurize natural gas to become Compressed Natural Gas (CNG); Compressed Natural Gas (CNG ) Vehicles require a special fuel delivery and filling system; when the system is built far away from the natural gas pipeline network, it is called a natural gas vehicle filling sub-station system; [0003] Chinese patent document CN1486409A discloses a hydraulic CNG refueling substation system. The CNG transport ...
