These simulations can predict large area-wide power outages caused by resonant swinging power flow in agreement with actual historical outages. Similarly, the same mathematical equations have been programmed into the Power System Stabilizer (PSS) subroutines of the modern voltage regulator.<\/p>\n<p>PSS can modulate the synchronous machine&rsquo;s voltage to instantaneously take power from the system or put power into the system by varying the angle between the magnetic moment of the rotating field and the rotating magnetic field of the three-phase electric system reflected in the voltage on the stationary part of the synchronous machine. If the adjustments of the PSS are set correctly, then power swings into or out of the synchronous machine will act to dampen the system-wide resonant power swings and improve system stability. If the adjustments are set incorrectly, then the opposite is true.<\/p>\n<p>PSS equipment provides stability for generators of any size that are connected to the transmission system.<\/p>\n<p>&nbsp;<\/p>\n<\/div>\n                    <\/div>\n                            <\/div>\n        \n            <\/div>\n    <\/section>\n\n<div  data-block-id=\"hammer_block_cb9a7397442e4e3103c854bcd677724a\" data-block=\"container\" class=\"block block-container container\">\n<div  data-block-id=\"hammer_block_a0bc07befaf72d84d4156885033a6256\" data-block=\"media\" class=\"block block-media media\"><div id=\"hammer_component_69d4dae989979\" data-component=\"image-video\" class=\"component component-image-video image-video\"><figure id=\"hammer_component_69d4dae989990\" data-component=\"image\" class=\"component component-image image\">\n        <picture class=\"picture\">\n            <img decoding=\"async\" width=\"300\" height=\"124\" src=\"https:\/\/www.baslerservices.com\/wp-content\/uploads\/2025\/07\/PSS_trace.webp\" class=\"img\" alt=\"\" loading=\"lazy\" title=\"\" srcset=\"https:\/\/www.baslerservices.com\/wp-content\/uploads\/2025\/07\/PSS_trace.webp 650w, https:\/\/www.baslerservices.com\/wp-content\/uploads\/2025\/07\/PSS_trace-150x62.webp 150w, https:\/\/www.baslerservices.com\/wp-content\/uploads\/2025\/07\/PSS_trace-414x171.webp 414w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\">        <\/picture>\n\n            <\/figure>\n<\/div>\n<\/div>\n<\/div>\n\n<section  data-block-id=\"hammer_block_4581148a0fb8b216728ed2c9244600db\" data-block=\"text-2\" class=\"block block-text-2 text-2 bg-light spacing-top-small spacing-bottom-default\">    <div class=\"wrapper\">\n        \n                    <div class=\"columns single-column\">\n                                    <div class=\"column\">\n                        <div id=\"hammer_component_69d4daea53a58\" data-component=\"rich-text\" class=\"component component-rich-text rich-text\"><p>Basler Services has the tools, techniques and engineering expertise to correctly measure the system resonant frequencies, generator frequency response and set the programmable constants.
