Embodiment Construction

[0014] The present invention acquires and transmits command information in real time by directly collecting data from the bottom layer, uses DDE (Dynamic Data Exchange, dynamic data exchange mechanism) communication mode to extract analog quantities and state quantities from MACH2, and transfers event information by means of an embedded dynamic library. Take it out from MACH2; then send the above data to the data acquisition and monitoring system using standard protocols. On the basis of not adding external node equipment, the original MACH2 hardware platform is used to realize the access of MACH2 to the data acquisition and monitoring system.

[0015] The original MACH2 platform uses the Suitelink protocol when sending information such as analog quantities and status quantities. This protocol is a non-standard protocol and cannot achieve open interconnection. In order to send data to the data acquisition and monitoring system, it is necessary to take out the corresponding ana...

Abstract

The invention relates to a method for accessing an MACH2 in a high-voltage direct current transmission system into a data collecting and monitoring system, and belongs to the technical field of high-voltage direct current transmission control. According to the method, analogue quantity and state quantity information is taken out from the MACH2 through a DDE communication interface of the MACH2 in a DDE communication manner; event information is taken out from the MACH2 in a dynamic library embedding manner; the information is transmitted to the data collecting and monitoring system by a standard protocol; and meanwhile, when the data collecting and monitoring system has a control operation, the data are converted into a data format which can be identified by the MACH2 and are transmitted to MACH2 equipment. According to the method, command information is obtained and transmitted in real time in a manner of directly collecting the data from a bottom layer; an original MACH2 hardware platform is adopted on the basis of not adding external node equipment; and the data transmission reliability and instantaneity are ensured.

Description

technical field [0001] The invention relates to a method for connecting MACH2 to a data acquisition and monitoring system in a high-voltage direct current transmission system, and belongs to the technical field of high-voltage direct current transmission control. Background technique [0002] In the DC transmission system, the control system platform adopts the technology of Modular Advanced Control HVDC (High Voltage Direct Current) and SVC (Static Reactive Power Compensation) 2ndedition (the second version of Modular Advanced Control HVDC and Static Reactive Power Compensation, referred to as MACH2) technology. , It needs to be connected to the domestic data collection and monitoring system and the power grid dispatching system, so that the control center and dispatching operations can normally issue commands and receive various information. [0003] MACH2 is mainly composed of standard industrial main computer and various PCI boards, in which various application software ...
