Various embodiments of the present invention provide systems and methods for data processing. For example, a data processing circuit is discussed that includes a data detector circuit, a detector mimicking circuit, and an error calculation circuit. The data detector circuit is operable to perform a data detection process on a first signal derived from a data input to yield a detected output. The data mimicking circuit is operable to process a second signal derived from the data input to yield a mimicked output. The error calculation circuit is operable to calculate a difference between the second signal and a third signal derived from the mimicked output to yield a feedback signal. The feedback signal is operable to modify the data input during a subsequent period.

A simulator running on a single computer may be configured to appear as multiple users simultaneously initiating Internet requests from separate user environments. An engine of the simulator may communicate with a browser to appear as multiple users each having access to a local defined user account or profile in a computer environment. The simulator may be configured to maintain different user profile data for each user appearing to operate within a separate user environment. The simulator may be configured to simulate a user logged into a particular desktop environment that initiates a browser session and then initiates Internet requests via the browser. The simulator may also simulate at the same time a different user in a different user environment initiating a browser session and initiating Internet requests via the browser. The simulator may be configured to appear as multiple, separate users initiating Internet requests from multiple, different user environments.

The invention discloses an intelligent substation simulation system based on a panoramic replace mode and an integration testing method for the intelligent substation simulation system. The intelligent substation simulation system is characterized in that the panoramic data simulation system comprising special third-party devices or PCs (personal computers) replaces actual secondary equipment of a substation, all interactive data of information of the total substation are simulated by SCD (substation configuration description) files imported into the total substation, information interaction between the intelligent substation simulation system and tested equipment is carried out, and the correctness of configuration of the tested equipment and even the integral system, the correctness of virtual terminals and the correctness of special properties are verified. The intelligent substation simulation system and the integration testing method have the advantages that the fixed simulation devices replace large quantities of actual engineering equipment in the integration testing method in the intelligent substation panoramic replace mode, troublesome operation for panel transportation, system construction, network connection and the like in an integration testing procedure is omitted, adverse effects due to errors when large quantities of engineering devices are manually configured can be avoided, an integration testing process is simplified, a large quantity of testing time is saved, the integration testing efficiency is improved, integration tests can be carried out in a large scale advantageously, and requirements of large-scale construction for intelligent substations are met.
