The frequencies of the fluctuations near the relaxed state of reversed field pinch (RFP) plasma in the presence of a stationary toroidal flow are investigated using magneto-hydrodynamical (MHD) theory in the approximation of the infinite aspect ratio and finite resistivity. We treat the fluctuations as MHD waves and derive their dispersion relations at the edge plasma. It is shown that there exists a new fluctuation mode with low frequency in the presence of a stationary toroidal flow, and that with the plasma resistivity it can be unstable. The dispersion relations of the new fluctuation mode and other MHD modes of the compressible plasma are obtained. The magnitudes of the frequencies are estimated using the parameters of TPE-RX, MST and RFX devices.
